ELI5: Why do people buy cars based on top speed, when legally there will always be speed limits?
gpt
If a car's top speed is 100mph, the engine is going to be straining pretty hard at 75, but if it can go to 200, it will do 75 easy.  It's sort of like if you have a shitty stereo and turn it up all the way, it'll sound terrible.  A good one can go way louder than you'd ever want to play it, but it will sound great at the same db as the shitty one, if that makes sense.
