Those "toys" are vehicles too.
I am with you regarding the yahoos that are riding 2 and three abreast and blocking traffic for no good reason other than they are being idiots. I'd react the same if it was a car or a motorcycle.
When I am on my way to work and a particular stretch of road does not have a marked bike lane, you can either wait behind or go around. The lanes are generally wide enough to allow you plenty of clearance to go around.
Otherwise, I'll meet you at the next red light (grin)
That's already been tried (grin).
