The Washcycle makes some good points

There are some things to quibble with here, but in general it has a lot of good advice and, at the very least, brings up things one should think about (quibbles below). I couldn't get to the comments, but that's probably a good thing.

• I wish he'd mentioned that drivers turning right need to turn from the bike lane.
• It's rare that a driver who brushes a cyclist gets a ticket, let alone loses their license.
• No one gets charged with a three-foot violation - even when they crash.
• I find this claim "But inconsistent risk-taking as you zip through traffic puts more-mortal riders at peril, because it makes drivers jittery and annoyed whenever they see someone on two wheels." hard to believe. But you should ride in a safe manner. I don't know why he didn't just say that. [And isn't consistent risk-taking worse than inconsistent risk-taking?]
• I do think sidewalk cycling is occasionally appropriate.
• I don't think you're foolish if you don't wear a helmet - but you are probably making yourself safer if you do. Wearing a motorcycle helmet to walk to the Metro probably makes you safer too, but I don't think you're foolish if you don't.
