Hello,
I've tested the car and there are few issues worth noting/fixing:
1) COG is too high, car tends to flip in each corner, COG should be lower
2) Weight of the vehicle without fuel & passenger should be 790 kg
3) Car should have ABS
4) Car should have front & rear anti-roll bar
5) When left side driver is selected, the dash stays on the right side
I hope this helps with your further development, all the best
