Adaptive Cruise Control?

Anything new on his subject. Any new news, hearsay, what ever?

Not a thing. We live in hope, although it's very unlikely that it will be retrofittable.

I am waiting too. I know they have said it is in the timeline. It is one safety feature I would really like, particularly if I keep the Model S for a while as I expect. I was hoping it would be rolled out this summer, but there are so many irons in the fire with supercharger roll-out, China, Model X.

Keeping my fingers crossed.

I really don't think Adoptive cruise control is a safety feature. Rather the opposite. It can make people rely too much on the machine rather than being vigilant themselves.

It's bad enough that airline pilots are quickly losing their skills due to the automation of flight. All of these "safety aids" are crutches. I am not talking about airbags, ABS, traction control. These devices/systems you can't humanly do. Paying attention to the traffic around you, is your responsibility. Oh wait, this is the United States, we aren't responsible for anything we do....

"We wouldn't need all these dang-nabbed 'nanny systems' if people would just pay gol-darned attention to their driving" doesn't cut it. The inescapable reality is that a large percentage of drivers, for a large percentage of their driving time, will not give driving the full attention it deserves. No amount of preaching (or, e.g., tickets for using phones while driving) will change that behavior. We need nanny systems, and we need them now. Superior beings who never, ever need such systems can, of course, turn them off.

@Pettifogger + 1,000^n :)

The same tired reasoning has been given for many features that are now standard in cars. Glad adaptive cruise control is coming and I hope it is integrated with a collision mitigation system.

And yes those superior beings who never ever make a mistake or never ever even for a second get distracted can not buy the option or turn it off.

I'm shocked people are still debating this. Every safety study I have seen that compared the identical model with and without adaptive cruise control/collision prevention system has in average about a 20% less chance of being in an accident when the vehicle is equipped with that feature.

It also could have prevented the July 4th accident where an entire family was killed when the Corolla they were riding in was rear ended.

My mistake. The reduction in the accident rate for the same vehicle with and without automatic braking is 14% and not the 20% I quoted earlier. I'd still have this feature than not.

Good article Web, however the thread is about adaptive cruise control, not a bunch of other "safety" features.

From your article, indeed it looks like there are some "safety" features that are not all that safe. Automatic braking does look like a good one to have though.

I would be interested to see what the stats are on adaptive cruise control.

Bottom line, none of us pay as much attention as we should when driving two ton missiles around. Want to scare yourself? Glance around at what other drivers are doing when you are at 70 MPH right beside you....

@Pettifogger,

Approximately 1.3 million deaths occurred on the world’s roads in 2012 putting it in the top 10 causes of death.

"Pay better attention" is no solution.

Luckily, autopilot will arrive to the Tesla line soon and hopefully it will be backward compatible. Until then adaptive cruise will have to suffice.

Whether or not (my) crash avoidance systems ever come into play while I'm driving, I will gladly accept the predictably lower insurance premiums commensurate with their availability in the vehicle. Even more, I want the person following behind me, merging into my lane, or doing whatever they're doing while texting about their morning breakfast burrito to have autonomous braking, blind spot warnings, etc as well.

I suspect ABS in another car has saved a few innocent bystanders from being taken out and nobody here is calling it a nanny. Still, like parking sensors, if you don't feel you need them and also don't feel they'll be an asset upon sale or trade-in, don't order the additional safety features...or turn them off if they become standard equipment.

@GAGSTESLA: They are related. Adaptive cruise control by definition slows the car down if traffic ahead stops and auto braking is basically that same feature set being used in an emergency situation. I bet when Adaptive Cruise Control is offered in the Model S it would be offered along with the emergency braking functionality. The discussion is related and on topic.

@GAGSTESLA: PS: I think that study I quoted actually gives the results for vehicles with just adaptive cruise control and vehicles with adaptive cruise control with emergency braking. There was a measurable difference crash rates where the vehicles with emergency braking had fewer accidents and injuries.

Basically for the most part it is the lower end vehicle that only offer adaptive cruise control without having emergency braking tied to the same system. If you look at virtually every other car over $60K that offers adaptive cruise control, emergency braking is offered as a part of it as the system ties into the same radar system with software actuating the brakes in certain situations.

Oh and I just found it. Look at the chart below for Mercedes. They list the results for the same model with adaptive cruise control but with and without auto braking. When auto braking is added to the feature set the rate of accidents went down by about 7% and the amount of property damage claims dropped 12%.

Basically even with just adaptive cruise control the accident and property damage claim rates drop but they drop further with auto braking. All in all both are very good things to have when available.

I have had it for the past ten years. It makes a big difference. I engage it as soon as I pass 20 m/h. It maintains a safe distance in rain, sun, fog or even when I just sneeze. It stops and goes under some of the worst conditions to keep me safe. It is the best safety feature I have ever had in the past 40 years of driving.

WEB_SRFR That chart is for collision avoidance systems, i.e. put on the brakes when about to hit something, NOT adaptive cruise control.

@GaryREM, the chart doesn't make sense unless it includes adaptive cruse IMHO.

@Edward Why? I've got collision avoidance in my Infiniti. It will apply the brakes and avoid hitting the vehicle in front of you and has nothing to do with adaptive cruise control. ACC is totally independent and maintains a speed if conditions permit while ensuring you maintain a minimum distance while cruising. The collision avoidance works with ACC turned off.

There is absolutely no mention of ACC in the article.

Pettifogger, your are correct, preaching isn't going to solve/reduce the problem, but much tougher standards to get one's license will.

Casting opposing opinions aside, the mortality rate per mile traveled in Germany is far less than it is here in the states. This is despite the fact that they drive much faster on average. The have essentially the same cars we do if not many that are even faster than what we have. So what is the difference, they take driving more seriously and there is a lot more involved getting a license than here in the states.

Creating more and more systems that take place of stuff you should be doing, is only going to make the problem worse.

Just saying with two columns (with and without auto brakes ) the without still shows a reduction in damage so something must have an effect (like adaptive cruse) otherwise what is the column for? Could be wrong since it lacks context and as you say no mention of ACC.

Forward collision avoidance can give audible warnings without auto braking or can give auto braking. Those are the two cases I believe as explained in the article.

The crucial question is whether you'll be able to blame the ACC for rear-ending the car you were tail-gating! If it has the responsibility, it should take the blame, after all. ;/

@GaryREM: They are basically both part of the same system. You have radar and in some case an optical camera to augment it as is the case with the more sophisticated implementations found in higher end cars and then you have a bunch of software logic that governs acceleration and braking.

Basically when you have the sensors (radar, optical cameras, IR, etc.,) you have all you need for adaptive cruise control to be implemented along with emergency braking. It is all part of the same package/system and the chart I posted is to illustrate:

1) Adaptive cruise control systems reduce the likelihood of accidents when comparing the same model with and without it

2) Adaptive cruise control systems reduce the likelihood of property damage when comparing the same model with and without it

3) Adaptive cruise control systems reduce the likelihood of injuries in accidents when comparing the same model with and without it

4) All 3 are reduced further when adaptive cruise control is implemented with emergency braking. In fact I don't think any premium car over $60K implements adaptive cruise control without also incorporating the extra logic software for emergency braking.

I bet when this feature is added to the Model S it will be a state of the art system similar to what Mercedes has that integrates both radar and optical imagery from several sources.

Forward collision avoidance can give audible warnings without auto braking or can give auto braking. Those are the two cases I believe as explained in the article.
. Although everything WEB_SRFR says is true, after some additional thought, I believe you are correct. The ACC may not even be in use when the CCS warns and brakes or just warns without the ability to brake.

Until you have a car with it you don't understand. Talking about it with out experiencing it is like never haven driven a Tesla! Just drive it and you will know it is MUCH safer. And Human ability is not as good as Human ability plus ACC!

Having said that, I would still buy A Tesla even without ACC.

Given the iPad like control panel and cell phones it's become a necessity to have
Emergency braking and acc.

Though apparently the adoption of seat belts has made people feel safer
And drive faster. I expect acc and emergency breaking will increase
The use of distracting tasks.

All of these accident avoidance systemsare are bad for business. Repair shops, car rental facilities, insurance companies, lawyers, physicians, hospitals, ambulances, tow trucks, mortuaries, flower shops, caterers, paper goods suppliers, beverage warehouses all of these businesses would be drastically affected if we stop getting into accidents.

If they're not outlawing cigarettes, which kill people and have no redeeming qualities whatsoever except for tax revenue and supporting workers in the industry, then surely we can take one for those who are standing by waiting for us to kill and maim each other on the highway.

Accidents are good for business, they're good for the economy, they're good for the community. So support America, drive like an idiot today!!

Lots of people on the roads supporting America, J.T..... ;-)
