What would happen if you didn’t need that second car?

For some households, having access to two vehicles is essential. Our communities, jobs, schedules, and infrastructure are often built around the assumption that we can drive where we need to go. Second Car Math isn’t a call to get rid of your car, but an invitation to keep the numbers in mind.

The graphic looks at what you could save by replacing a second car with a combination of biking, transit, occasional Uber or taxi trips, and car sharing. Using the example in our breakdown, even with two Uber or taxi trips a week, the alternatives could save $262 a month compared with owning a second car.

Maybe it doesn't work for you today. But jobs change, people move, transit schedules change, and our needs change with them. If the opportunity ever comes to scale back to one car, the math might just be on your side.
