Not everyone has a garage with an extra set of rims, and a jack, and the physical dexterity to switch between winter and summer tires. And although a service station can do the switching, you still have to have a place to store the wheels that you are not using, and have a way to transport the tires to the service station and back home, and you have to have the spare $$ to pay the service station.
All season tires, albeit a compromise, allows you to drive in all conditions, without any of the storage problems and tire changing problems. It is why most vehicles come from the factory with all season tires.
Sports cars typically come with summer tires, because if you have $100,000 for a sport's car, you will likely have some other car that you will drive when it snows, and you probably want your sport's car to not be held back by using anything other than summer or competition level tires.
