While I’m tempted to point out that cpiatal accumulation has had myriad positive externalities that raise the quality of living & thus accomplish more humane ends than any philanthrophy or do-gooderism I’ll agree with you that one way to encourage people not to drive is to invest less in roads. The main reason I bike to work or take the train is because it’s a complete nightmare to drive from the southern suburbs into downtown. Off-peak I can get to drive to work in 25 minutes, and that’s what I would do if I didn’t have to go in rush hour (when it’s more like 75 minutes). I’ll add that I never, ever would have considered biking 13 miles each way if it were not for cycling infrastructure: wide streets in Dedham, bike lanes in Roslindale, and the separated paths along the Jamaicaway as well as the Southwest Corridor. Downtown is still a semi-nightmare along Mass Ave, but I’m optimistic that we’ll see progress there thanks to the good work of folks like yourself. Increasing the appeal of biking to work is an interesting one. In my mind there are two steps:1) convincing people it can be done at all2) convincing people that it is safeunder #1, friends and colleagues are routinely stunned to learn that I bike to work. I’m not particularly fit or outdoorsy or green’ or anything like that. and they are shocked to see me on the bike in the rain and cold. but (#2) they still think I am nuts, that it is way too dangerous especially in the city. one of my colleagues bikes from Lexington to Alewife on the separated path and then takes the T to work because he refuses to ride in Cambridge. There is not much I can do to convince them otherwise, and honestly it doesn’t seem very safe to me sometimes.
