Traveling within the US? Whether you are going to drive your own car or find a ride with someone else who has a car, Ridester can definitely help you.

"Ridester is a road trip marketplace where travelers can offer or find rides within a feedback-rated community."

If you have a car, you can offer rides. The people who ride with you will cover the cost of gas. And yes, you can choose who will ride with you. Check the details on how to offer rides here.

If you do not have a car, you can request a ride or check out the available offers here.

It's a cost-effective and safe (well, relatively) way to share the cost of gas with someone else who would be going in the same direction. It's also one of the cheapest way to get to your destination, if you do not have access to a car.
