The cybertruck has two separate steering motors for redundancy. Passenger jets have been doing "x-by-wire" for decades. Properly engineered it's as reliable as mechanical linkage.


Two motors is great and all, but that only provides motor redundancy and won't help if something happens to the electrical system.

Planes are fly by wire but that's because they literally have to be, no amount of gym time will let you move the rudder on a 737 by hand.


The 737 is not fly by wire.


Ok fair enough, it is hydraulic assisted instead but for the point I'm trying to make it's essentially the same thing in so far as it requires power.
