I bought my house on College St when it was a one way street, and over the past seven years or so I've been around for at least half a dozen speeding car vs. parked car collisions. Since the street has become clogged with parked cars, I haven't encountered one such incident. In my experience, a crowded street causes drivers to slow down and NOT smash into my or my neighbors vehicles. I'm glad to no longer live on a one-way thoroughfare. And I've never seen cars parked on College Street blocking driveways - a word to the (not-so) wise - I drive a Jeep, and my front bumper is already plenty banged up. If you DO block my driveway, I'll move your car out of the way :-)
