But in practice idk if they always have actual hydraulic brakes. I’d still think they do, even if there’s also regenerative braking.

I thought most of the input from the driver (steering, breaking etc) had a layer of computer between the input interface (steering wheel etc) and the actual moving parts.

I’m thinking at some point it will probably be that you’ll need to hand over driving to a computer whilst in a city or smth.

That is an interesting solution on how a first push for self driving cars could look like.

I saw a documentary some years back about self driving trucks in Australia, a company used them instead because it was safer for a computer than a human to drive through the desert.
