On VirtualTourist.com, these warnings are given about traveling in Boston. Notice how most of them say "don't drive there." This bolsters my case for making non-professional driving illegal in Boston. Only business vehicals should be driving in the city. Everyone else can park in Brookline, Netwon, Cambridge or Braintree and take the T in. This may seem draconian, but I assure you everyone will benefit from this.
