adaptive cruse control

by installing an adaptive cruse control function to the model s may allow the car to achieve more efficiency with the regenerative breaking. it also makes the model s a much safer car to drive.

Disagreed on all points. This feature is for the people who don't want to drive, they want to be driven.

I respectfully disagree with the disagree. Computerized ACC can accelerate much more smoothly and efficiently than a human being this saving fuel/energy. Also it may be advantages to slow down by easing up on the accelerator without regen sometimes to maintain distance and a computer can make those decisions much more effectively to save energy. Thus ACC would get more milage which increases the appeal and maybe even helps pay for the ACC. Perhaps someone who has driven a car with ACC can elaborate on the fuel/energy savings.

I'm sure everyone has seen the dash indicators showing the fluctuations in MPG as you press and release the accelerator. ICE have offered them for awhile now. An ACC will beat you every time in fuel efficiency.

In addition, Tesla can show off their smarts & offer the next evolutionary leap in ACC. How about an ACC that also does passing of cars on the the highway ? It could also improve safety , ( a lot of people do not know how to pass properly, tailgating & coming back over too soon.

AAAC (Advanced Adaptive Cruise Comtrol) with a (turn on/off) passing feature would also be a nice intermediate step toward auto-pilot cars as well as help to collect data on such a feature. It would also help to
slowly get people used to autopilot cars & make a great purchase option and beat the competition ! Go Tesla !

I'd love to have AACC; I love driving but in traffic nothing would beat the ability for my car to seamlessly and automagically handle predicted traffic flow and adjust its own speed for me.

I would love adaptive cruise control but ANY kind of braking makes your trip LESS efficient... regenerative braking is more efficient than dissipating the energy as heat but coasting to slow down, when possible, is still more efficient.

ACC would certainly make drafting easier and more efficient.

With ACC, if braking was needed, the software should be able to do it more effectively than the driver, since the software should be able to more quickly detect changes in the distance to the vehicle in front faster than human observation.

On long distance trips, this could even result in some (small?) increase in range.

A lot of other cars have the ACC, even my VW CC.
ACC works wonders in cueing, and we have å lot of that here in Norway.
And for those wanting to "drive" themselves, theres an "off switch"
A real drawback on the car, but we will have to live with that.
I heard the car is prepared for this, so maybe later....

Both PDC and ACC should have been included from the beginning in the Model S as standard. Both are safety features and PDC increases range in the highway. I think that Tesla engineering resources were stretched and they focussed on what is important.

I just got mine without the PDC. I am just careful, but once I get going, I do not miss either features. May be with highway driving I would miss the ACC.

Safety is not a magic word for 'must have'. Safety can be increased by numerous things; it is not necessary or possible to implement them all. The saftest car would be a self-driving tank that didn't exceed 20 mph.

@BH: saftest, say what? Short for safetiest? ;D

Weight adds to the kinetic energy of any vehicle moving. As in E=.5*M*V^2
Energy that has to be brought down to 0 in case of an uncontrolled stop.
If your tank does not deform during this process, then its surroundings will.

Safety is a matter for the occupants AND OTHERS on that specific date, time and place...

A heavier car makes you feel safer, but is not safer for overall traffic safety. Hence the weight race for cars (yes, comparable with weapons race).

Neither of those systems are safety features. They are crutches for people who don't want to drive, they want to be driven. For that, I suggest a chauffeur.
If you are not controlling the vehicle you are in, then you are not a driver, you are a passenger.

My current car has cruise control. I have never used it, nor will I ever use it. It is uneccessary.

Don't knock it till u try!

@Vawlkus
Ridicilous. PDC has nothing to do with driving or willingness to drive. Not all cars are equal in line-of-sight from driver perspective, sometimes parking spaces have crow bars/fenders as separators that won't show up on rear camera, parking may happen in a hurry (when other drivers are impatient) or sometimes people may just have a bad day (unconcentrated). PDC is a nice assistance, not an annoyance, to many.

@Vawlkus,

I don't know how much long distance driving you do, but when I'm on a long trip I find cruise control a very useful feature to reduce stress in my right leg. I have no opinion on ACC.

Adaptive cruise control makes cruise control safer by automatically slowing the vehicle to give the driver more decision time to avoid or pass slower vehicles. It does reduce right leg fatigue on long trips, and ACC does make using cruise control a bit safer. It is also lazier and requires less driver involvement since you don't have to manually take control by pushing the decelerate button, hitting the accelerate button, or deactivating it and using the pedals. It's a nice feature to have but only gets used on long stretches of road.

Some driving enthusiasts (Vawlkus) abhor the concept of piloting an epic car with cruise control on. That's because they always want to be in control of what the car is doing; soaking in the whole experience and actually driving, instead of merely keeping the car between the lines and avoiding slower traffic. These people live for a twisty mountainous road and a sports car to blast through it with.

I have a new wrinkle on this. The lack of ACC was the most serious concern for me but I ordered it anyway. I have specific problem. My right ankle is fused and doesn't bend at all. Operating the accelerator on the Model S is noticeably more active than on a standard car because it doesn't coast. I realize you can set it to coast more but that decreases range. It is harder for me to drive and use the accelerator, and the more i do it the sorer i get, so being able to set it on the freeway and forget about it saves me a lot of pain, literally.

Take a look at this thread which talks about adding an accessor to your floorboard so that you can drive with your left foot. It may help: http://www.teslamotors.com/forum/forums/making-model-s-accessible-disabl...

BTW, ACC can apply regen differently from pedal actuation.

In those cases where it is more efficient to coast, ACC can be designed to suspend regen on a millisecond timing basis, and then reinstate it when deceleration is required.

There is a cool opportunity there for efficiency that cannot be matched by manual operation.

acc is , to cruise control what power brake is to old fashion regular brakes. a obvious progress that HAS to be implemented to any luxury car (and is).

There is a time and a place to engage the ACC but having it takes nothing away from an avid motoring enthusiast.

I test drove a Telsa, flew across the country to do so. I had plans to buy one. The positives were what I had expected. The missing features left me so disappointed, I was not interested in buying one any longer. The concept of 'no compromises' and 'the best car you can buy' I considered to be completely false. The premium Luxury cars offered FAR more in the way of features and accoutrements.

I see that recently Telsa has added several of the missing items. However still on my list are heated steering wheel, adaptive cruise, video while parked, air conditioned seats.

Selling my Escalade to buy a Telsa, I don't not want to feel like I'm missing things. I long for adaptive cruze and I think it would be a great feature that makes sense for a technology company.

"in all the dimensions that matter". Your requirements are, to be kind, superficial.

Different strokes for different folks.

For some, the "improvement" to the automotive vehicle that the Model S provides is not enough because it lacks all the "features" that would make it as "automated" as the competition.

IMO, Model S makes driving fun again. All these features that the others have, may be because driving those ICE vehicles just isn't "fun" anymore.

Good thinkin'.

Drive from the Atlantic to the Pacific, then talk to me about long distance driving.

All ACC does is encourage INATTENTION behind the wheel, which I have issues with, since driving a car is akin to operating a guided kinetic missile.

@Vawlkus

+1

I share your opinion. :)

Nothing substantive to add. Just another vote: Adaptive a must have for this consumer.

Hey, look! It's Adaptive Cruise Control Day!

AGAIN!

AGAIN, AND AGAIN!!!

Is Adaptive Cruise Control something that could possibly be added via a future software update? Or would it require hardware?

Radar in the bumper, and linkages to display computers.

It would require a plastic front nose so that something could be put behind it to sense what's on the road.

For those who think that ACC isn't a safety feature, just wait until somebody cuts you off at 70mph a few feet in front of your bumper and immediately slams on his brakes full force. It happened to me. I had ACC. I'm still alive. There was no accident. And it wouldn't have been humanly possible to get my foot to the pedal any faster. Plus, the brakes were pre-pressurized because of the sensor so when I did touch them, I didn't have to slam anything. So in less extreme conditions, it makes it easier to brake.
