My one-off experience. Parked my car once for a long holiday (two months). Mice chew through the main wiring loom behind the dashboard and urinated over electronics (urine is slightly corrosive). 1) no mechanic has time to repair single wires 2) dashboard removal is more than day of labor 3) main can bus failures are hard to find and require pulling modules till canbus high/low get the right voltages I’d say a hard NO towards flybywire brakes.
