I mean it's all in software right? So if a system crashes and there is a relay that tells the motor to spin, not spin (which is probably not how variable speed works) but follow me = then if that subsystem crashed (some exception is thrown) and the code cannot be recovered - then whatever relay state the vehicle was in may just stay that way. ICE vehicles may be much more complicated, and we all know they're going away, but let's not dismiss these real issues.
