>I tried FSD on the $200/month plan and dropped it: It makes the car unsafe. To command a lane change you hold down the turn signal stalk. If you fail to hold it down long enough the car suddenly swerves back to the lane it was in. This is (to say the least) disconcerting at 80 mph.

This isn't true. You just tap the stalk down until it clicks. Sometimes if it detects issues in the other lane it will not complete the lane change and go back into your existing lane. But you do not have to hold it down the whole time.
