It's an AMAZING benefit. You get in your car in the morning and it says stuff like "we've improved the ability of your auto dimming headlights to detect oncoming traffic", or "we've added a setting to automatically turn on your headlights when your windshield wipers are on", or "we've added an ability to move the blindspot camera window".

A traditional car never "improves". If your windshield wiper rain detector sucks, well too bad. Maybe when you buy another car in 10 years it'll be better. Where in cars with OTA updates, they are constantly improved. Like I said, it's an amazing benefit and I would imagine most other car companies are looking to adopt this model.
