The fact that you named this mod version 0.1 actually offends me ! It is way past 0.9, it is brilliant and you created it from completely nothing, well done ! Model is very nice and I'm really impressed by sound, superb success with sound. Physics are always #1 subject in AC, and I think it is a blast, I feel like I'm really doing everything and car is listening to me, it feels like early 90s supercar IMO, and I love it - it is car and not a spaceship after all. It has some problems with coasting, but if you have at least a little idea how to adjust differential, then there is no problem because it is totally adjustable. 10/10 car, I'm honestly impressed.
Anyway, thanks - your input throughout was invaluable :)
