That already doesn't exist in a lot of cars (drive-by-wire).
- sandworm101 11y agoI have yet to see a production car that doesn't have manual brakes, either hydraulic in the case of master-slave cylinders or mechanical in the form of parking/emergency brakes, that can be engaged without electricity. There might actually be a rule about that, else parked cars could start drifting away if their batteries run down.
- woofyman 11y agoMany cars have electronic parking breaks.
- sandworm101 11y agoBut is there a model that, if you disconnect the battery, has no brakes? The few electronic parking brakes I've seen fail into the on position, much like truck trailers and or traincars. They lock if they loose voltage/pressure from the controlling system. And even those cars had master cylinders under the pedal.
- woofyman 11y agoThere are no break by wire production cars in the USA. Infinity sells the only steer by wire car. It uses clutches that engage a direct mechanical link if the electronics fail.
