I actually think this is a great idea. Hear me out.
They fit the hardware that you can't touch while the Motor plan is active, but when the right to repair legislation kicks in, and we start debating whether we actually own the cars we buy, all these scumbag practices will mean that any car outside of the Motorplan should be able to run cracked OS's and everyone gets free BMW features on their cars after motorplan expires.
I vote they keep going for a bit, then they get their asses handed to them with out of maintenance plan service options and 3rd party features.
