On the other end of the scale we have Tesla, which clearly does very little testing of their media systems, and pushes updates over the air, so things get broken or changed with every update. But "hey, it's not a big deal, we'll just push another update in a month!" - that's absolutely not acceptable with cars.
For example: https://medium.com/@michaelmeier_90534/tesla-model-s-is-grea...
I would be absolutely furious if my car did this. I would rather have a shitty system that stays shitty for the lifetime of the car, than have a good system that gets broken through an over-the-air update.
