The Short Answer

Because otherwise it's not very sympathetic to the car's mechanical parts. For instance if you say "Well my highway has speed limit of 70mph so I'll buy a car that has a top speed of 70mph". Well great, but in order to do highway speeds you then have to be absolutely hammering the engine, with your foot plastered to the floor just to keep up with the traffic. A car that can do 150 will be just cruising nicely at highway speeds, while your 70mph top speed car will be screaming, with the exhaust pipes glowing, smoke pouring out of the bonnet, and everyone in the car being shaken to death. Just because it can do it, doesn't mean you will, it just means that at the speeds you're *meant* to travel at, it won't be overstressing the engine.
