How do autonomous cars deal with cheap or worn tyres? Is there still a lot of allowance for braking distance?

Or weather/road conditions. Reaction time is irrelevant if you happen to be driving over an irregular/wet/oily/sandy/etc section of roadway at the moment maximum braking force is demanded.

A burnout at the beginning of every drive cycle would do wonders for calibration.
