The evidence here doesn't seem that strong -- just manuals that hint that "10-foot lanes are as okay as 12-foot lanes" and the odd (non-randomized or large scale) study here and there. I'm also curious whether a good part of the author's conclusion is driven by his like of bicycles and pedestrians. I live in a city, and almost exclusively walk and bike, so I'd be on his side. But a key part of his argument seems to rest on it potentially being able to free up more bike lanes, about it being faster for pedestrians to cross the street. If part of the motivation is that towns need to be more pedestrian and cyclist friendly (potentially at the cost of cars) that's fine, though I would appreciate it being explicitly pointed out. Right now it's a bit confounded.
