Limited slip differentials in all their varieties still don't do what stability control and traction control do. You need software for the systems to perform in a way we have come to expect.

A car without any software at all would be carbureted and have no ABS or traction/stability control.

I'm not saying computers don't do these things better.

> A fully mechanical system saw limited automobile use in the 1960s in the Ferguson P99 racing car, the Jensen FF, and the experimental all wheel drive Ford Zodiac, but saw no further use; the system proved expensive and unreliable.

Those systems were used in aircraft, not cars. The operation was significantly different as well.

Anyone who owns a car with mechanical fuel injection will tell you how much more reliable carburetors are.

My point is simple: we have used software in automotive systems for decades and those systems have proven to be reliable. Removing all software from a car will not make it safer just because new automation systems are poorly built.
