You never know, some cars drop 1 or 2 mph going up a hill when on cruise control. If a newer model is behind them and doesn’t do that then maybe it will try to overtake.
Or if a self driving Mercedes is behind a self driving Tesla and they have 0.5 MPH difference in actual speed even if both are designed to go the speed limit.
I’ve seen these things around LA a few times in the last couple of months. As pictured they have huge sensors all over them. Hard to imagine they could be much less safe than the average LA driver.
I think he would argue that if someone is going to travel at that speed anyway, we would prefer they use driver assistance tech as that makes it less dangerous.
I think there’s something to that in the longer term - for example if people are aware that a self drive system will never overtake because to do so would exceed the speed limit, then they will overtake themselves and probably do so in dangerous circumstances where the autonomous system would not. I’m not thrilled about people setting Tesla’s current system at over the speed limit though.
