I think you are incorrect, the station wagon evolved into the mini van and SUV. What passes for a 'full size' car today doesn't have the capacity for a family even with a hatchback.
Sure most people don't use their car to tow today and I don't think towing was a primary use in the past either. The difference is that few cars today have the capacity to tow even a 1000 lbs trailer.
Cars spend most of their existence unused and parked, so why does anyone even need a car? When they are being driven usually it's just the driver, so why have more room than one seat? etc.
Unless we're buying multiple vehicles, we tend to buy them for the maximum likely use case rather than the minimum or average one.

Excellent post. I NEED a truck to do my job. When they build an electric vehicle that will do what I need it to do both personally and professionally, I will seriously consider buying one. Not to mention the fact that when all aspects such as life of the vehicle, battery replacement, etc. are considered, electric vehicles pollute at least as much as regular vehicles.
