Tesla unilaterally decided to push out a refactored UI to my old Model S a few months ago, changing the location of numerous functions to new sub-menu paths, and rendering years of muscle memory useless.

Not only do I have to re-learn where everything is, but older memories interfere and confuse every time I try to access an infrequently used function.

This experience has been irritating at best. It has felt extremely unsafe on more than one occasion.
