Money. Charge for useless features, then charge more to let people buy out of them.

Fuck the following:

Flush door handles

Tablet screens that are not integrated into the dashboard

Motorized air vents

Glove box doors that require using the infotainment to open

A lack of keyholes or metal keys for at least one door

Cars that cannot be put into neutral without power

All the goddamn telemetry that you can't shut off

Subscriptions for basic features

Aaos in any car

Gear shifters that are entirely non intuitive

It gives them something else to fix and make money on when it breaks. Traditional headlight bulbs are like $10-20 and easy to replace, but newer LED headlight harnesses and their replacement can be hundreds.

Because there are no innovations left to make, the design of a car is pretty well established.
