Traction issues happen on all wheeled vehicles, motorcycles are just extremely sensitive to them. A few years back I got rear-ended (at low speed) because of pretty much the issue mentioned: fully painted crosswalk in wet conditions, the car behind just slipped on it and couldn't stop, ended up in the trunk.

Maybe they were just a terrible driver. I live in a cold U.S. State and have never slipped on Ice and RearEnded someone. I have never been in a situation where I slid down a hill and couldn't stop, mostly because I drive like you are supposed to in the Winter. Self driving cars will invalidate the need to worry about traction as they will force themselves to adjust to conditions instead of humans choosing to drive inappropriate for current weather conditions.

Or maybe they were not, and slippery roads are a significant issue.

If everyone drove 1mph do you believe there would be as many car accidents from slipping? Nope. This type of event occurs because of human misjudgment.

[mvid]

Yes, and the world would also be a safer place if people went 0 miles per hour and never left their houses, but both situations are pointlessly unrealistic.

We won't see a major population of self driving cars for decades. There are perhaps a dozen live models. We have millions of human driven cars now. This is the problem we solve for, not the ideal future fantasy.

I think you missed the point. I didn't give the 1mph example to imply that it should be the way it is. I used it to point that you are incorrect in saying "or maybe they were not." Accidents, mishaps, misjudgements, say what you will, but they are all just human error, not "acts of god." So you are incorrect to say they were anything but that, no matter how much you wish they were.

We also solve for the future all the time, constantly, every day. We build solar powered devices to stop global warming and pollution. Every day we work towards a "future fantasy." It is like saying we don't need roads because we have these horses we have been riding. Why build rubber wheels when our wood carriages work just fine. Why build a smaller computer when this massive datacenter works just fine.

This wasn't winter, there was no ice, and it was low-speed urban driving. The wet crosswalk simply had close to no traction.
