Eli5: Why do cars have four wheels instead of three?

It’s mostly a stability thing. With only a single wheel at the front, vehicles are more inclined to roll when turned at high speeds. This is to do with how the centre of mass “shifts” under the effect of inertia, but you can think of it as trying to balance a marble on a plate in a moving vehicle, having three wheels reduces the wheel base and that’s like using a smaller plate
