I think she meant until it gets prohibitively expense to drive a private vehicle. Probably something between $5.00 and $15.00 per gallon of gas would do it. Personally I think pricing gas inversely to the fuel economy of the vehicle using it would be appropriate. Have a car or scooter that gets 100 mpg? Buy gas at $1.00 per gallon. Have a hybrid that gets 60 mpg? pay $1.67 per gallon. Have a compact car that gets 30 mpg? Pay $3.33 per gallon. Have a Hummer that gets 5 mpg? pay $20.00 per gallon. You could set gas prices at say $100, divided by the mpg of the vehicle buying it. That way the gas guzzlers most responsible for the the scarcity of supply would pay the majority of the cost for everybody.
Three things would happen. Consumption by gas guzzlers would rapidly decrease, people would stop buying them, and there would be an immediate and earthshaking scream at the American vehicle manufacturers, demanding that they fix the obscenely poor fuel efficiency of their vehicles . The oil companies could be allowed to keep a particular number of pennies per gallon beyond their cost, and the balance would be collected as a tax which would then be rebated to buyers of fuel-efficient vehicles, solar water-heaters, solar power systems (or it could be used to lower the price to the consumer of all those things), and also to provide a trust fund to build up the infrastructure of fuel-efficient public transit modes, like PASSENGER TRAINS. And absolutely none of this will happen as long as W is in office.
