A friend and I go to Vegas (from the LAX area) once or twice per month. We'd travel three to four times per months IF I wasn't the only one driving.

Are there any 'regular' traveling clubs/car pools in LA?

If not, we might start one. We travel east from the 405 via the 105, north on the 605 east on the 210 and north via the 15. We could pick anyone up within a quarter mile of said route.

Any ideas on liabilities/problems with such a club/car pool?

In Vegas we could drop individuals off within a quarter mile of the 15 up to 7 miles north of downtown.

Pick ups would be at the same locations as drop offs or in downtown Vegas.

THX in advance for any ideas/suggestions.
