As a long time motorcyclist, I am very conscious of the problem of vehicles turning left across my bow when I proceed through intersections because I am invisible, and I take lots of extra care in those situations (including, of course, 4 way stops). Likewise, I don't expect people to notice me as they pull out of driveways, step off the curb, etc..

But I think this is the first time I've EVER had someone turn with me and just ignore my existence.

I am a big fan of the well placed slap, and use it when I can. In this instance I was a bit too busy looking for my escape route/ ensuring I wasn't eating pavement to get a hand up and on her flank. The worst part was how genuinely unapologetic she was when confronted. Ugh!
