Works for me. Has it always been broken for you? Tried turning off mods?

 

was always broken without mods too

 

Reset your input maps. Deleting or renaming "Settings" in your "Documents/BeamNG.drive" folder is one way to do that (with obvious consequences). (and disable all mods)

EDIT: apparently this is another, better, less-nuclear way to reset your input maps. (and don't forget to disable all mods for testing)
