Brake Check
I didn't really notice this until I started cycling, but see it so frequently now. And I used to be an offender when I drove a zippy little sportier car, unlike now in my stick shift SUV. But Brake Checks...
I am regularly scared spitless by drivers that feel that they need to go from 30mph to almost zero (no complete stops in Oregon...) at intersections. Is this a fundamental flaw of Oregon drivers and their lack of understanding of physics or poor depth perception, or do you see this, too?
I usually have my commuter helmet on in the mornings, with the 600+ lumen light on it. Those brake-checkers get a little longer glance as I ride by than the less racy drivers. I'm just hoping beyond hope that the light will give em a headache....
