Good news is that all bmw's come with all the options just turned off via software.. So be smart guys, this is called hacker news for a reason... Just buy bare metal bmw and turn all luxury options on... (and BMW is traditionally very dumb on security)...
I can't just "turn on" adaptive headlights because the vehicle doesn't have the necessary camera to scan the road for oncoming cars installed.
I can't just "turn on" adaptive cruise control, because my vehicle doesn't have the necessary front radar installed.
I can't just "turn on" the HUD, because my vehicle doesn't have the necessary dash components physically installed.
The number of different hardware permutations of most modern cars is eye-watering. For most options, if you didn't get it installed from the factory, you're looking at an expense retrofit.
