Sure there are buses and bikes - and scooters. But in Southern California, most people drive to their destinations, and the price of doing that is headed north.
"We're seeing gas prices head straight up. We saw double-digit increase over this last week and that's a pretty strong increase for Southern California," Jeffrey Spring of the Automobile Club of Southern California.
Spring says the price of gas usually starts to creep up in April or May when refineries switch over to summer grade gasoline. But AAA's latest surveys show the average price for regular gas is now at or just below $4 a gallon.
The average price of a gallon of regular gas in Los Angeles is an even $4 a gallon - up 16 cents in one week.
Gas is a penny less in Orange County, and in the Inland Empire, a gallon sells for $3.95 a gallon. In Ventura County, a gallon is $4 - up 17 cents in seven days.
The experts say this time around, you can't blame the run-up on Americans using too much gasoline.
"Compared to last year, we've used less gasoline overall in this country than before, and so it's kind of funny that the prices are going up even though demand has been going down," Spring said.
