Because here in the USA you NEED a ginormous pickup or SUV to drive one person to and from work!!You can also drive small. I simply do not understand why the Kei car is not more popular in first world countries. Max speed (electrically limited) 87 mph. Weight under a ton. Easily seats 4 adults. You can park it nearly anywhere.
More seriously, I'd go for a very small and economical car but I have no need for one. My wide wouldn't go for one. She drives a small SUV. She has trouble getting in and out of a small car. I have a truck because occasionally I need a truck. Most of the time it sits in the driveway and doesn't use any gas. When I need to go somewhere by myself I almost always ride one of my scooters which is way more fun than driving a cage and uses less gas too!
