Wfooshee..... Explanation aside, I get the positive points but I just can't get past the lack of trust in stupid drivers doing stupid shit all the time... They will never cease to astound me in their totally unconscious ability to do sporatic things that will KILL ME.... With so many people paying more attention to their phones, putting on makeup, reaching back too feed their kids, spilling coffee on themselves what have you.... I have lost any Faith inn others driving cars around me in closer quarters where I'm always going to end up the loser
The reality is that most drivers are not homicidal maniacs, and I only very rarely encountered a driver who tried to close the gap. Most drivers see you coming and move to let you through.
Granted that was in another country but even here, even when I have risked trying it in Oklahoma, I have been surprised by how many drivers make space.
If this comes, providing it is accompanied by a decent public awareness campaign, there should be few problems. Once motorists realize that bikes only contribute to conjestion if they choose to stay in line, then most are more than reasonable. Fuq the rest, just keep your eyes peeled.
