Women-Only Buses

From the NY Times:

But many women complain that not all the contact is incidental. Among the 22 million passengers who use the bus and subway system daily, women say, are lecherous men taking advantage of the cheek-to-jowl conditions to leer and grope and then quietly disappear.

In response Mexico City has implemented women-only buses, though for only four routes so far. I've heard first-hand stories from women who had very unpleasant experiences while riding public transportation in that city, and this is certainly one way to deal with the problem. I wonder if it'll add up to twice as many busses on the roads, some half empty. There is also a big problem there with pickpockets. They should have separate busses for people with wallets that are sticking out of their back pockets and those who wish to steal them.
