The new chaos vehicles required some tweaks and I might have to alter how the lever sends in the data for reverse.
I thought it was already fixed (it is for the FPS testing) but I will double check, don’t know if you are on an older build or not.
The start button doesn’t really have a use for these cars as I am not changing gears.
Edit, actually I did miss a difference with the chaos vehicles on the VR side, I just uploaded a correction that fixes it.
