Gee, the bike was going too fast, and the car was in a hurry, also, and wanted to bypass a light.
I actually see a lot of people in my area bypassing slow, or backed up traffic lights.
(It's not like I live in a major metro area, traffic gets a little heavy, but I wouldn't consider it a traffic jam.)
Usually they'll try to slip through the nearby corner gas station, and come out the other side. Since I fill up at that station pretty often, I've damn near been run over a couple of times by some jerk that couldn't wait 15 seconds for a light....and was doing 45 mph between the pumps.
Today, I was waiting for traffic to turn left into a shopping center entrance. (In a turn only lane, with a traffic light.) A green arrow would have popped up in a little while, I had a green light....but oncoming traffic was too fast, and close spaced. I waited...with 5-6 cars behind me. When I did get a chance, I went...and almost collided with some moron in one of the through lanes, who was making his own turn lane by going around the line of cars, and me, and 'blazing new territory'.
Damn near hit the idiot, since I wasn't really expecting somebody to pop up alongside of me, and pass me, as I was making the turn.
Since it was a larger older car, all banged up....I didn't feel real confident the guy had assets or insurance, so I braked.........
Sure would have been lovely to see a cop nail the moron, though!
Taking shortcuts can get you killed, or kill somebody else. It isn't worth it.
