Perhaps they hope it will increase demand for flex-time or distance working options. This certainly is already happening with lots of desk jockey jobs where broadband and a cell phone can essentially replace the office cube. But there's obviously a limit to how many 9-to-5 commuters can be taken off the road, and it seems like traffic hell is already enough of a disincentive to staying off the roads or altering your schedule if possible, so I can't say I get it either.
