The Toyota Prius is designed to excel in both city and highway driving, but stop-and-go driving tends to reduce fuel economy more than highway driving:

In city driving, the engine frequently starts and stops, using more fuel as the engine constantly switches on and off.
On the highway, the Prius can maintain a consistent speed, allowing the hybrid battery to assist more in maintaining fuel efficiency.

Improving city driving efficiency:

Avoid unnecessary idling.
Use the EV mode in the Prius when possible to minimize gasoline consumption during short trips.
