Well we do live in a city neighborhood and don't have to drive much.
Car insurance on two cars not used daily $400/month here, gas immaterial. But the cost of the cars (paid off) was so much money, if spread over a 15 year life (mine will go longer maybe, but that's unusual) would add another $125 each, so $650 plus gas and maintenance (less maintenance cost because cars were bought pretty new).
My daily commuter is a good electric bike, $2,000 plus electricity (I could charge it at work tho) and maintenance. I don't know how long they last, so can't estimate a per month but insurance for a year costs less than one car costs for a month.
Transit pass here about $50 a month. But buses are terribly infrequent.
