Tire friction has no effect on vehicle motion

I can run simulations with PxVehicleNoDrive and they work as expected. However, the terrain (ground plane) and tire friction attributes seem to not affect the vehicle’s motion.

I thought it was a bug on my end until I tried running the example snippet SnippetVehicleNoDrive_64. Changing friction had no effect. Setting gravity to nearly zero yielded results consistent with physics i.e, the wheels spin without locomoting forward.

Any help would be appreciated.
