You might be shocked to find out that speed limiters in cars are a thing: https://en.wikipedia.org/wiki/Speed_limiter

Many rental car companies actually do restrict where you can drive your car, for example, by forbidding off-roading, or from taking the car over state or country borders. Most restrict rental cars from being used for commercial purposes (meaning in this context, food deliveries or rideshare services).

If you want to treat your car however you like, you can buy a car and abuse it to your heart's content.

If there were just 2 car manufacturers (which there is in the GPU space) I would agree with your counter argument. But there are plently out there. If Ford said you couldn't drive your car in the snow and labeled their cars as such at point of purchase well then you are free to by GM, Toyota, Tesla, Mazda, Kia, Honda, Subaru, etc etc etc etc.

Wait until you find out what happens to your warranty if you take your car to the track…

You've got the analogy wrong. It's more like: Want to drive your car to deliver pizza? That's market segmentation.
