Also bad: When a software update moves essential elements around.

For the last three years I've looked at a particular location in my car for the clock. Then a software update moved it not just to a different location on the screen, but to an entirely different screen.

Three years of muscle memory is probably going to take another three years to un-do.

(For those of you who don't understand why a clock is an essential part of driving, it's so I know if I can park in a 9a-4p zone, or if it's the time of day when I can use the reversible lanes in my direction of travel, or if I can use the lanes that are HOV sometimes and HOT at other times, or a hundred other things.)

The same software update moved the wiper locking controls (for car washes) from a button on the left steering column stalk to a menu option four levels deep on the center screen.
