The Airport Commission is going to vote tomorrow on a plan to eliminate shorts. Instead they will have a $14 minimum and allow a $3 charge back for the $4 airport fee.
Since I don't play the airport I'm going to link you with John Han's blog The San Francisco Taxi Industry Advocacy Jounal.
Personally I think the best option would be the New York plan where a starter checks with the cab to find out where the driver is going then gives a short ticket for certain areas. There would be no time limit so there be no reason to race.
If you don't like the plan, I think tomorrow is the last chance to protest.
