What would the monthly subscription have to cost to make it financially worthwhile? I drive a bought and paid for car and if they could move me to and from work for $200/month our household would happily become a one car household. That bought and paid for car still costs me $75/mo insurance, ~$40/mo gas, amortization of the purchase price is probably in the $150/mo range, and since it’s 8 years old increasing maintenance costs. Additionally it will eventually need to be replaced which costs many thousands. I don’t think a subscription model is too far fetched at all. We definitely intend to at least consider being a one car household, even at current ride share prices, when the current secondary car reaches end of life.
