Done a few 130mph sprints but couldn't imagine cruising at those speeds. Pretty much a guaranteed death if even the slightest thing goes wrong.
I'm sure if I had a car that can do 250 I'll convince myself to max it out sooner or later though.
The reason why a lot of cars are speed limited to around 130 is that most tires arent rated to drive above those speeds without risking a blowout.
150 is already ridiculously inefficient, and you outrun your lights at night... 250 is kinda nuts.
You don't have enough time to stop if something shows up in your lights. you don't actually outrun them.
