Now that is truly 'green'. Really, these type of markings have been around in Europe for years and I think they work better than white. Besides, white is getting kinda dull these days, don't you think? Thank you to StreetFilms in NYC for this short video. Judging from the response by drivers, the message is getting through.
I believe, these could work for Toronto. I am jealous and so are others even the fine biking folks in Portland.
