Not sure if that's a serious question, but your driveway might lack a proper foundation, so the surface is moving and cracks. Also, it's likely not concrete, but tarmac (which is much softer).

A significant number of American driveways are concrete. I'm not going to look up numbers, but I would have to believe that more are concrete than asphalt/tarmac. Unpaved driveways could outnumber both, who knows, but most people with paved driveways have concrete.

I think that depends on the region and weather differences. In the northeast at least, asphalt seems to be a lot more common than concrete.

I’ve never understood why people so frequently choose poured concrete over cheap interlocking pavers. Where I live, it’s extremely common to see someone pour a concrete driveway then promptly cut it up because they forgot something.
