On a possibly related subject, the system of charging drivers in central London for using the roads there during weekdays, in effect for a few years now, is interesting and I wonder if they couldn’t do it in New York and other congested cities of the world. Not that possible in Los Angeles because of the need to have a car just to get around and I never thought San Francisco city limits were ever that congested except for a short spate in the morning and the evening. The Brits are talking about supplanting the cameras now used to determine the cars that drive in the fee-zone with some kind of satellite tracking devices that would change the current flat fee of 8 pounds to a graduated charge depending on where each car went. Profits would go to better public transportation and bike routes.
