Latest DMV numbers for SF
The latest Department of Motor Vehicles numbers on vehicles registered by county in the state show that SF's totals have remained constant. Last year the city had 461,827 motor vehicles---I don't include trailers in the count---381,737 autos, 59,751 trucks, and 20,339 motorcycles/motor scooters. This year's total is virtually identical: 461,536, with 382,167 autos, 58,641 trucks, and 20,728 motorcycles/motor scooters. This is the first time that the total has been constant from one year to the next. Past totals have fluctuated by as much as 18,000 a year, but the trend over the last ten years has consistently been more motor vehicles in the city, from 451,879 in 2000, the earliest number I have.
