conversations to avoid...
one key conversation to avoid is the CAR to BIKE conversation
those who commute via car have an opinion
while
those who commute via bicycle have another opinion

the conversation is as useful as two people with opposing views on Abortion trying to have a pleasant exchange
there will be no pleasant exchange
both parties will walk away hating the other

personally...
I am not sure why car drivers take it so close to heart
while I can see why the cyclists do... because it is their life that is at the bumper of the self centered car commuter

is there such a thing as a SMART CAR?
