Well said Lisa.

This kind of stuff comes up all the time in two-wheeler forums, and it's always difficult to advocate safe, defensive riding without seeming like we're defending the cagers or blaming the victims.

The way I put it is an amalgam of a couple of popular sayings. You've got to ride like the 1% of cagers who see you at all, are aiming for you on purpose.

I still maintain that the OP did nothing that contributed to the situation she described, and that filtering on the right on a bici is sometimes, but not always, appropriate, safe and legal. (On a moto, it's sometimes, but not always, appropriate and safe. )
