Where is WheeledVehicle.h?

I Cannot seem to find WheeledVehicle.h.

UE4 API Wiki (https://docs.unrealengine.com/latest/INT/API/Runtime/Engine/GameFramework/AWheeledVehicle/index.html)
says :

Runtime/Engine/Classes/GameFramework/WheeledVehicle.h

But there’s no file like that.

Any idea?

Thanks!

It’s now a plugin, you can find it there:

Engine\Plugins\Runtime\PhysXVehicles\Source\PhysXVehicles\Public\WheeledVehiclel.h
