The average US commute is 27 minutes https://www.census.gov/library/publications/2021/acs/acs-47.html https://www.census.gov/library/publications/2021/acs/acs-47.... which is around 15-20 miles one way. That means at least half of US workers have enough range on a 40 mile battery to do the full commute. More to the point though, even if you have a 40 mile commute, reducing gas consumption in half is still a massive win.
