I suppose some of the variation between Boston drivers and the rest of the country is due to the progressive Massachusetts Driver Education Manual which I happen to have in my top desk drawer. Some of the Tips for Better Driving are worth considering, to wit:
[173.15b]:
“When competing for a section of road or a parking space, remember that the vehicle in need of the most body work has the right-of-way.”
[141.2a]:
“Although it is altogether possible to fit a 6′ car into a 6′ parking space, it is hardly ever possible to fit a 6′ car into a 5′ parking space.”
[105.31]:
“Teenage drivers believe that they are immortal, and drive accordingly. Nevertheless, you should avoid the temptation to prove them wrong.”
