I think you misunderstood me, but it was my fault. I didn't explain very well what I meant.

I was referring to the situation where there is a bike trail along side and parallel with a busy main road. A side road with a stop sign meets the main road. The side road crosses the bike trail at the stop sign. The car is trying to make a right turn onto the the main road, but must cross the bike path to do so. With busy traffic the driver stops, and looks to the left, looking for an opening in traffic to make his right turn. The bike approaches from the car's right, sees the driver stopped at the stop sign, waiting for traffic. As the biker crosses in front of the car (who is at a stop sign), the car driver (who is looking mostly left) suddenly sees a small opening in oncomming traffic on the main road and goes for it, without really looking to his right.

The biker is within his rights, crossing on a designated bike path, in front of a car that is stopped at a stop sign. The car driver needs to look both ways before making his right turn. But the driver is only thinking about other cars, so only looks to his left where auto traffic is approaching. The driver forgets that he is also crossing a bike path. Many drivers seem totally oblivious to bikes.

I've experienced this from both sides. I once almost hit a bike because I stupidly failed to look both ways before making a quick right turn where the road crosses the bike path. I've also had some close calls in similar situations when riding a bike. Now I try to be more alert both when riding or driving.
