In all 4 base environments (Canyon, Stadium, Valley, Lagoon), the order of the wheel states in memory is the same as TM2020 (FL, FR, RR, RL), however the rear wheels are swapped in the VehicleState implementation for MP4. Getting a value like vis.RLGroundContactMaterial instead returns the state of the rear-right wheel, and vice versa.
