I Absolutely LOVE the game BUT.. in Every game there are cons... I suggest better engine sounds. Also I suggest that you guys add Airbag functionality... also.. maybe in the vehicle config. menu for every default vehicle to have a crash-test dummy to sit in the front seat and be smashed around by the airbags.. that would be fun to watch... also gives it a more realistic crash..
All of these have been suggested before, the sounds will be improved later but both airbags and drivers / dummies are unlikely to be added any time soon due to the extra CPU load they will create.
Wait... What? Download TelemaX's sound mod and you will no longer be complaining about already-suggested features.
