I'm really curious how Tesla tested this update. I'm not a UX designer myself, but have worked with some really great ones, and there's not a chance in hell they would've put anything as drastic of a change as this into a customer product, especially if it has safety implications, without extensive testing.
What? Tesla has thrown multiple serious FSD changes over the fence into vehicles with little more than a few days since the previous releases (multiple changes to phantom braking, being one of them).
Their attitude to testing, safety or otherwise (i.e. braking) has been horrifically lacking, at best.
I'd be surprised if this move saw much more than a User Story from the MMI PM before going into production.
I'm also curious if the designer(s) involved have tested it much themselves, or even drive Teslas at all --- some interesting comments on this recent article https://news.ycombinator.com/item?id=30018763 revealed that Windows' UI designers don't even use Windows themselves.
It would be unfortunate, but not entirely surprising given what we've seen, if the people responsible for these changes hadn't even tried them in their own cars for a reasonable amount of time. I'd say at least 1 year is reasonable, since all weather conditions need to be experienced.
