it looks like not a bug but an existing issue is revealed.
with 1.8.1 we added the ability to override clutch input even if auto clutch is on.
apparently an old clutch axis binding was creating incorrect output and we weren’t aware since we were using auto-clutch.
so it is not a throttle issue, the clutch is fully pressed so the vehicle can’t move at all.
if you remove or set zero scale for the input axis below then the issue is gone.
