Compared to tailgating and slashing through traffic moving a 70mph?
While talking on a cell phone? (Just a little perspective, let's also
include "loaded vehicle weight".)

It also made me think about why drivers get so angry with cyclists.

A lot of the time, they are assholes who are scapegoating where they
know they can get away with it.

And
once again, these drivers' anger spill over to safe cyclists.

Amen. See above. But at least now we have cell phones that take
pictures and send them instantly. Makes it real easy to call 911.

How do people feel about licenses to ride a bike ?

Covered by your state DL. Bike = vehicle, infraction = ticket.

Don't invite additional harrassment of cyclists, please. --TP
