I've been obsessing over my safety score since I got my Y and tesla insurance in May, but as I'm in CA it doesn't impact my premium. With the recent update for night driving I did one night drive which took off a few percent. Also found I was more hesitant to brake at amber lights, would rather speed up. Would regulate speed through freeway interchanges by adjusting the autopilot speed dial to avoid being dinged for fast cornering if doing it at a sensible speed manually. Would use autopilot in on the freeway if I see a slowdown ahead but dial speed way down to avoid the stupid hard braking it would do if left unchecked. It really doesn't look ahead.
I feel so liberated now I've switched off safety score! I don't think I'll feel comfortable with it all round until all cars have something like it and all cars talk to each other.
