We see signs all over to "watch" for motorcycles. That's fine; but the cyclists need to "watch" too.
I had a biker tailgating me for several miles recently. He wasn't much over a car length behind at about 60 mph.
I tried using my warning flashers to get his attention, but he ignored them. I allowed extra distance in front so I would be able to slow a little more gently; but if a kid had suddenly run out on the road, there would have been a mess on my back bumper.
This is merely a friendly suggestion that everyone needs to do his / her part for safety.
