What I quite don't understand is how they can get a 600 km mileage with the Rimac using approximately the same battery capacity (93 kwh) as the Model S. I see that they use LiFePO4 batteries, but are these batteries lighter/kwh (higher energy density) than the Li-ion batteries in the Model S, or is the car itself significantly lighter than the Model S?

It costs over million, so they have probably used a lot of carbon fiber and other exotic materials in it to make it light. It also looks to have very low CdA (A in particular, it is low and quite small car, not much bigger than Roadster), so in higher speeds it probably causes less drag.

I just noticed that it doesn't have rear window at all. I'm not sure how legal that is in passenger cars. It's important to see what is happening behind you so that you don't change lines in front of some fast-moving 18-wheeler. It certainly wont be easy to park using only those tiny side-mirrors, so it probably has backup camera. If it doesn't then I think that's illegal here (at least it wouldn't surprise me at all if it is).

One other thing: it seems to have odd seatbelt arrangement, I see a seatbelt buckle in the door. One of the concept drawings shows five-point seat belts. It would be nice to see that with more detailed explanations what to expect (dimensions, interior designs etc. in more engineering point of view).

This also sets a kind of bar for next generation Roadster. It needs to be a bit more than current generation Roadster to make people think its worth buying.

As Elon has often said, all that has gone before is preamble to the
Bluestar, what he hopes will be the first affordable EV - presumably less than $30K, and CAPABLE, like the Model S, of taking trips.
He has also said that its appearance depends upon the achievement of a much more affordable battery on the market. Therefore, it is quite impossible to predict exactly when it will appear in showrooms.
Elon has made guesses, based on previous price reductions of batteries, but they are only guesses.
