I recently (about 400 miles ago) started riding with a rear blinkie turned on all the time. I've noticed drivers generally seem to treat me different with the light. Now I ride mostly on rural roads and drivers are very, sometime too , courteous. But these same folks change when I ride into our little town. In town on a 4 lane boulevard I'll get passed, buzzed, several times by drivers in my lane. There is no shoulder so this means they are much closer than 3 feet when they do this.
The other day, I rode up this boulevard for the first time with the blinkie on. I didn't get passed, in my lane, one time. Everyone passed me by using the other lane. This is the fist time I've had anything objective to lend to my theory about day time use of blinkies.
Anybody else experience this?
