The camera is vibrating or something, either it's orbiting the car when you first start, or the car is vibrating and turning around. Very strange, running 3.0.2 stable official,

ok seems to be the car itself shakes and rotates slightly if you don't move, when first starting.

Yes, this is a known issue in the vehicle body simulation. I haven't had time to look further into it, hopefully Odino and I will have some time soon to figure out what can be done about it.

Addresses vehicle vibration issue BastiaanOlij#1
299a010 
Mitigated abnormal vehicle vibration of issue BastiaanOlij#1 by adjusting CollisionShape dimensions. The shape seems to significantly impact the strength of vehicle vibrations in Godot. This depends primarily on whether the CollisionShape length extends beyond the wheel placement, followed by a marginal significance of ColllisionShape width, regardless of wheel placement. CollisionShape depth is seemingly unimportant.

The shape also seems to affect whether the vibration is introduced to situations of braking to a stop, and continuing to apply the brake when stopped.

Changing wheel_friction_slip could reduce vibrations, but doing so directly impairs handling.

Hey @vrai17 , please check in 3.0.3 RC1, we did do some fixes in Godot itself that should improve some of the final shakiness we had.
Though for me it was working well in 3.0.2 after the fixes we applied to the project itself.
