thank you for that information I will look into it I would love to do those long distance ridesYes of course. If you commute long distance like that, or plan a driving trip, look up websites for car pooling. You can post a trip and people will respond. Zimride has been bought by Enterpirse Rental Car so it's not available to the general public anymore, only to Universities and institutions that signed up for the service. But there are other websites that the public can use.
From San Diego, if you plan to drive to Vegas, Phoenix, NorCal, definitely use car pools. They will at least pay for the gas.
A few times I even carried cargo for people. They would pay for an empty seat to use my trunk. I would fill that seat with a passenger, yeeha!
