DLC can be problematic but it can also be a benefit. An example with Tesla is that the Model 3 recently received an option to improve its off the line acceleration after Tesla monitored enough usage to see if there were any motor and battery issues in their new model 3. You'd have to wait to get a new car in the old world.

It has been very problematic in the case of Tesla, as they have stripped features from resold vehicles.

If I bought a car from anyone else, everything I bought the car with will be on the car when I resell it. I'm sure some people will tell me I just need to understand this exciting and innovative new paradigm pioneered by Tesla, but I'd like to think most people can understand how this is anti-consumer behavior and really gross.

How long until Tesla (or some other car maker) goes the EA Games route and requires pre-owned buyers pay fee to "activate" their car after the transfer of ownership?

My previous comment was discussing paid DLC - content that may require an active connection to check authorization for and may disable features if it cannot verify online that you have purchased.

Free DLC/software updates that do not have such a check would not be impacted by a loss of network connectivity, but thank you for raising that issue explicitly.
