I’m more concerned about the failure mode than the failure rates. Mechanical and hydraulic brakes can experience gradual failure, giving the driver a chance to pull over get the car repaired.
EVs usually have a single motor and a single inverter , both of which can fail suddenly. Electronics usually work perfectly fine until they suddenly don’t work at all (blown fuse, bad connection, blown capacitor etc)
How are they gonna build redundancy so that no single component failure means youre freewheeling downhill on the highway
Back in the day you had to have two distinct hydraulic lines, crossing over and serving 3 wheels each, so that you could still break if one went down, but you’d feel it.

Guess they’ll have at least 2.
Do people really think Professional Engineers are stupid?
No, but their bosses might be.
Yeah, they’d never put an unsafe vehicle into production. It would help boost confidence if someone explained what the backup plan is.
