Objectively, this shouldn't be too hard. In regular non-self-driving cars, your Traction Control already detects these things like slipping tire traction and automatically closes your throttle and reduces tire speed to try to save your life in rain/snow/mud.

traction control just reduces power when you spin the wheels. you have to spin the wheels first for it to detect it. (it's basically the reverse of anti-lock brakes.)

You don't touch the brakes going downhill in low traction. You, ideally, should never touch the brakes while going down hill in the first place...

this wasn't like I *hit* the brakes and had this happen, I put them on extremely gently only to try to keep from gaining more speed.

the fundamental problem that I don't see a solution for is that you can't tell how slippery things are until you're slipping. there's a particular condition with slushy wet snow on a warm road that can make things *extremely* slippery, about as bad as sheer wet ice. when you're in that situation, you need to go like half-speed or less and do things like brake and steer with *insane* caution. but you can't tell you're in that situation until you've already slipped on it. I don't see how the computer can detect the road slipperiness *in advance* and go the appropriate speed and use the appropriate pressures.

also, you mention traction control, but keep in mind that things like anti-lock and traction-control, which are already a form of self-driving, are already *worse* than doing them manually. threshold braking is so much better than anti-lock, in fact anti-lock is almost dangerous in slippery enough conditions, because you end up with basically zero braking. pressing the gas lightly is also better than traction-control.
