What are the best ways to improve the fuel efficiency of a Toyota Prius?

I'm interested in maximizing the fuel efficiency of my Toyota Prius. What are some specific methods or modifications that can help me achieve this goal?

Cruise control can help maintain a consistent speed and improve fuel efficiency on long drives.

Consider investing in aerodynamic add-ons like a rear spoiler or wind deflectors to decrease wind resistance.

Change driving habits by avoiding sudden accelerations and aggressive braking.

Regularly check and replace dirty air filters for better airflow and improved fuel economy.

Ensure that tires are properly inflated to reduce resistance and improve fuel efficiency.
