Wow, if that's our intersection filtering poster child we are all sunk.
Ok, so how does this filter thing work, I've squeezed between 2 lines of cars being cautious not to clip their mirrors or scratch their paint and I made my way up to the intersection, so now I'm sitting cozy between 2 cars that are totally aggravated with my presence and the light turns green !
:headbang: the race is on for the next light! Oh wait :| it's highly illegal to race, I better just ride regular speed and hope those guys I just passed don't cream me with their mirrors or crush my legs.
Oh oh, the next light turned green before I snaked to the front of the line :/ you know that game where the music stops and you have to find a chair real fast, but there are fewer chairs then there are people, now I'm the guy left standing.
... How is this really safer for anyone?
Short answer: it won't be until other people on the road get used to it.
