They don't. Everything is inputs to the redundant autopilot system;
stick and throttle are suggestions, not really commands.

This true when operating in normal law mode (99% of the time). However, when
degraded to direct law mode, the A-320 operates like a normal airplane. The
reboot is not because it can't fly, but because we like everything to work
so as to provide the safest flight we can (and we are lazy and don't want to
handfly a whole leg).
