Depends on the route they took. From the video I'm assuming they went through Brookline and down the Jamaicaway/VFW etc . Guessing about 16 miles but it would have been stop and go and no highway driving. The probably never got much above 50 mph. edit: Hey I just realized this wasn't my thread. It looks like we both posted this w/in a few minutes of each other.
