Earlier quoted context omitted.
There used to be a very few number of car companies who held a lot of power over dealerships and used to abuse that power, which led to laws protecting dealers in ways that at least arguably made sense at the time, but don't anymore.
Do we now have lots of new car company? ( i don't think so ) Does car company now have less power? ( with subscription and OTA updates , I think they have more power than ever)
Yes, we do. The "Big Three" of Ford, GM, and Chrysler now face significant competition in the US from Japanese, German, Korean, etc. carmakers.
