Chaos Vehicle bug in default behaviour

I’m not sure if this is the right place to report bugs, but seemed like the best category.
I’ve discovered that the chaos vehicle (both the default demo in 5.0 early access and the previous ones in normal releases of ue4) has some unexpected behaviour.
Adding a rotating platform to the scene and dropping the car on it (or driving on it) does not affect the vehicles position/orientation, the platform just spins underneath it without having any effect on the vehicle itself.
This behaviour works on the old system with the physx vehicle setup by default - as expected from a physics based vehicle.
I’m not sure if there is any way to fix it as a developer - I could not find any option on the blueprint, wheels, or actually any part of the chaos vehicle system that would make it behave as it should - rotate with the platform that sits on.
Any quick-fix ideas are welcome, but I think this should be fixed to be a default vehicle behaviour, just like in the old vehicle system.

Same issue in 5.1.
