I also lived in the Cambridge, and I am very familiar with the 47 bus leaving from Central. I also biked there a lot, and I can tell you that there were very few times where I needed a car. The only times I needed one was where I was going to the suburbs and the alternative infra is non-existant. For the majority of cases, the T + biking was more than sufficient. It is not about penalizing car driving. It would be a good start if the US did not subsidize car ownership. It the true cost of car ownership was put on those driving, perhaps cities would be able to finance better public transit...
