The average American household saves between $8,000 and $12,000 per year by using public transportation instead of owning and driving a second car.

What hidden car expenses are often overlooked when comparing to transit?

Drivers frequently forget parking fees, toll roads, vehicle depreciation, annual registration/taxes, interest on car loans, and unexpected mechanical repairs.

What non-financial factors should I consider besides cost?

Consider transit reliability, commute time difference, physical activity (walking), stress levels from traffic, ability to work/read on the train, and climate footprint.

Eliminating a second vehicle while combining public transit with a shared household car offers an ideal balance of financial savings and personal flexibility.
