My philosophy, too... but it can (and DID) go wrong for me. Coming around a sweeping bend at almost 40 km/h, I got double salmoned (2 salmons side by side) in a bike lane this week. One moved over, the other didn't react. The gap between us was closing rapidly as I realized that one of these guys was fixated on his front wheel or handlebars. I moved to go between them (no time to brake to a full stop) and shouted "heads up!". At which point the guy immediately swerved out of the bike lane and right into my front wheel. Boom, double endo.
