I don’t see what makes the Aptera good for commuting. As you say, the average European car is driven about 20 miles a day.
Most solar on a car will give the car at most 6 miles a day (Prius Prime). It's nice, but not life changing. But up to 40 miles a day is way more than 20. The average driver would never need to plug it in, ever, which is quite the difference. That is also true for Americans. According to the 2021 National Household Travel Survey (NHTS), the national average driving distance is 19.9 miles per day.
It’s not like the Aptera has a small footprint, either, so an Ami or Zoe or Mini or Inster will be better in urban settings.
True. It is definitely not a great city car, where the city is Manhattan or Boston. San Diego, though? Las Vegas? Phoenix? The vast suburbia?
And ultimately, of course, mass transit or public vehicles makes the most sense for day to day travel.
