Human variability and unpredictability can also be a source of creativity. But I understand you completely

I hope you never have to cross a street, or get anywhere near a car with a human behind the wheel.

Its terrifying; sometimes when I am crossing the street people accelerate, sometimes they slow down, sometimes they stop at red lights, sometimes they drive through them.

That's why I don't have a driver's license

Yes, but alas other people do.
