A sudden $.65/gal increase seems steep. There are, however, a lot of negative externalities—probably much greater than $.65/gal—from gasoline that aren’t baked into current prices. Other posts here reference significant savings from longterm health improvements. I’m all for public transit and California needs more of it. At the same time, gas is really bad and so perhaps deserves a stick, just like cigarettes?
