Cockpit can't control the wheels
I have tried to build a service vehicle which would have a cockpit that can raise up using piston. One of the problems I experienced is that wheels don't move when I try to control them through the cockpit, but the wheels work only when I manually override them through configuration.
I have tried setting the cockpit as main cockpit, didn't work. I also checked to see if there's power, if wheels have propulsion, everything is okay there
