New video of Tesla crash demonstrates the problem of semi-automated driving

This mirrors my experience of driving in America. People do not adjust their speed or following distance to the conditions. They drive like they have some sort of right to a road free of obstructions and to drive at the speed limit or above, no matter the circumstances. It's as if they expect the speed limit sign to adapt to the circumstances. They have the attitude, "Well if I need to slow down, why does the sign sa…

I think what's interesting here is it's likely the first instance where Tesla FSD has been involved in an accident which affected other drivers. [Edit] From the video the Tesla is making a lane change and stopping simultaneously which means there could be a case of the Tesla FSD/driver doing a unsafe lane change.[1] Most of the time FSD just wrecks the Tesla itself or injures the driver of the Tesla (i.e. running int…

FSD does not activate on freeways. This is not FSD. It's the same Autopilot that has been in use for many years.

Doesn't look like phantom break, which is usually very sudden and no lane change. Most likely the driver was hands off the wheel and was warned multiple times before the car pulled itself over.

The police report claims “Full Self Driving Mode Beta Version.”

It’s unclear because FSD is supposed to switch to autopilot on highways. The driver said it was in FSD mode but they may just not realize that switchover occurs.

And here is the whole problem. It’s not good UX.

I just did a 1500+ mile road trip over the holidays. During the drive, I was trying to figure out why old-tech (2005) cruise control worked so well. Even a 1 mph differential in speed is a car length change in following distance every 10 seconds. A 1/2 mph difference is 3 car lengths of change every minute. That seems like enough that would be annoying, but it obviously wasn’t when two cars are following each other b…

A 1 MPH pass doesn't take that long in absolute terms, but 15 car lengths (to maintain 7 car lengths in between at 70 MPH) still takes a solid 2.5 minutes to complete, during which you are nominally blocking the passing lane. (I say nominally because once there is a 2 car length gap between you and the other car, other drivers will be passing you on the right.)
