We're a one car family for two working parents and two kids, living in Pittsburgh (in the city, not the burbs). We make it work but there's a bit of Uber involved sometimes, and some compromises. Generally worth it - cars are both very convenient and a burden that requires ongoing care and feeding and money.

If we do decide we need a second car as the kids get older, this is _exactly_ what I want. No gas stations. Super easy parking. Low capex and opex. Awesome on all fronts. (But as a second car.)
