Average US driving distance is about 14k miles per year, or about 1200/month. At 30 mpg, you need 40 gal per month. Current price per gal in the US (according to AAA) is $3.193/gal, which gets us $130/month in gas.

Wouldn’t have to be crazy above average to get to $200/month. Or have a car with kinda bad fuel efficiency.
