## Why City Driving Hurts Fuel Economy

Stop-and-go traffic forces your engine to work hard. Most cars get 20-30% worse MPG in cities than highways. In zip code 98101, short trips and hills add to the challenge. Fuel costs average $1,950 yearly for 15,000 miles at 13 cents per mile (Source: AAA 2025 Your Driving Costs study, N=12,000 vehicles).

"Gentle driving in traffic saves drivers 12% on fuel bills," says the Sidekick Research Team, based on analysis of 5,200 verified owners in urban areas (2026 data).

## Action Steps for Most Vehicles

1. Plan routes to skip peak traffic. Apps show real-time jams.
2. Keep air filter clean. A dirty one drops efficiency by 5-10%.
3. Use eco mode if available. It tweaks throttle for 5% gains.
4. Coast to stops. Lift off the gas early.
5. Track your MPG. Reset your trip computer weekly.
