Very cool. I wonder if it will be limited to 135mph and if it will have the handling of a P85 or P85+. Either way I am definitely picking this game up. Hopefully we can tweak the color to match actual Tesla colors.
I "drove" it yesterday. Yes, it is limited to about 135 mph. The tachometer display hits the red line and the car stops accelerating.
The acceleration is pretty brisk and appears to be in the right range. Also it's a bit weaker in the top end, which is in line with reality. The motor doesn't overheat though. Regen must be set to Low; it doesn't slow down quickly when you lift.
I've driven the real Model S on a track, and the digital version definitely understeers more. I put some stickier tires on it, and then I found I was getting oversteer. Odd.
Incidentally I raced against a Tesla Roadster also (but not driving the Model S). Was fun to see it, looked pretty much exactly like mine. Did beat it though.
