I'm sorry but you're getting it completely wrong. Brake by wire isn't legal anywhere in any market of the world and consequently there are zero cars implemented this way - every car currently on sale everywhere has to have a physical connection between the brake pedal and the actual brakes.
Throttle by wire on the other hand - sure. Nearly all new cars only have an electronic throttle.
Steer by wire is making progress, with Lexus making the first road legal car that has a steering wheel that's fully disconnected from the steering rack, with only electronic control.
- klik99 3y agoThank you, yes that was probably literally the worst example I could have given. But isn't there famously brake by wire in toyota EVs? And that physical connection is required as a fallback?
- gambiting 3y agoYes, they always have a physical fallback :-) and don't worry the systems like that do exist just not with brakes - it's an easy mistake to make.
- iknowstuff 3y agoLexus has a backup mechanical link it engages when a fault is detected. The Tesla Cybertruck is the first vehicle on the road with no such backup. They rely on redundancy of motors, power, and compute instead
- gambiting 3y agoDoes it have a backup link? According to this video: https://youtu.be/agMrewRJTow?si=DrjfGsrKp5_ZazB- https://youtu.be/agMrewRJTow?si=DrjfGsrKp5_ZazB- There isn't a mechanical connection of any kind - the car just relies on triple(!) Backup for every component, including three fully independent power sources.
- dr_dshiv 3y agoLots of cars brake by wire -- but not through the brake pedal.
