At least on brake by wire ICE systems I could let engine braking slow me if the brake system fails somehow (even if I have to blow the engine to save my life, worth the trade).
A drive-by-wire system had better be a lot more reliable and also notice impending failures.
I feel like I have had several close calls that would have been accidents for sure had I been driving with power steering.
It's not a problem at those speeds, having it crap out when turning slowly and sharply around fast traffic is much more likely to be deadly.
There has been a number of plane accidents related to physical connection between the yoke and the actuators (cables loosing tension under high temperatures, or cut/trapped on a deck failure). Electric cables does not suffer that, and they are easily doubled.
SbW makers are already making software that does constant surveilance of the system, something that traditional systems has never done.
The number of dead people caused by the steering column going straight through their chest in a collision is huge. That shouldn't happen with SbW.
I hate the trend towards car controls in a screen, but Drive by Wire sounds like a real advance towards better cars to me. DbW without redundancies and continuous tracking could be a safety issue, but with them I don't think it's an issue. Fly by Wire has a good safety record.
Because there are dozens of people helping keep each plane safe.
