Why are sports cars so low to the ground?👀

Why are sports cars so low to the ground? It's the same reason planes aren't low to the ground. Like, if you drive a McLaren, you look for the smoothest road before you head out. But brands don't design it this way to look fly, they do it so it won't fly. Because at high speeds, air builds up under the car. And if that air builds up too much, it can lift the car off the ground just like a plane taking off. So the less air gets under it, the safer the car is.
