Lex might be right but if he is, he will be right for the wrong reasons.<br>When I began riding a motorcycle, I started watching dash cam footage compilations of accidents and oddities. My driving improved dramatically because I recognises the scenarios when there was a higher probability for a hazard to emerge. So many times it felt like I could see the future and preempt someone cutting me off etc.<br>One of those things was reducing speed and paying closer attention when cars in the adjacent lane in the same direction slowed down.<br>Tesla's now have had an update to slow down in these circumstances. The beautiful thing is that the car can detect hazards without drawing attention away from the road ahead or other hazards.<br>Most hazards are predictable and the data will allow for a computer to assign a probability to these outcomes and adjust driving accordingly.<br>Human behaviour, particularly on roads is not all that complicated.,(reply>), yeah it doesn't have to predict human behavior anyway, theoretically(not practically or applicable in all scenarios) it's possible to calculate a safe distance from other cars on the road accounting for how fast they can move and how fast the autopilot can react as well as move it's own vehicle where it would quite literally be impossible for a collision to happen even if the human driver intentionally tried to hit the autonomous car.<br>of course doing that exclusively would waste too much space and such so some predictability will be used as well but the point is we don't need to solve human psychology or anything like that.
