Hello, i tried making a car using vehicleControl. When i put all wheels together the vehicleControl doesnt react to .accelerate()
this is the first time im using vehicleControl and i couldnt find much on this issue anywhere.
here are some screens(to show that the wheels are actually physically connected + the terrain is also a physical body with mass 0) and code
