Just got back from two weeks in France, which was exceedingly French, figured I'd post a word here... (I always thought Ottowa was the dorky little useless sister of Toronto, I may have to revise my perception.)
While I know Paris quite well, it's quite flat, has a lovely bike-share program, clearly marked bike lanes, and all the concierges at the hotels encouraged me to rent a bike to ride down Champs Elysees (eet ees zee on-ly way to see zee Arc de Triomphe, bien sure!), I never got up the courage to attempt a two wheeled venture into Paris traffic. A discussion with a Parisian finally defined my general sense of foreboding - turns out the sane locals all walk, take the metro, or bus. Only crazy people, professionals, and idiot tourists drive in Paris. Cars or motos. When they "pull over" for any reason, they always do it IN the intersection, diagonally blocking two lanes with their confusion or waiting for some mysterious event to occur, resulting in an instant traffic jam.
Wasn't happy about coming back (they really could have tried harder on the bread for the flight from PARIS, come on), but while waiting to be picked up at the PIT airport, saw a bike cop patrolling the pickup lanes. REALLY made me happy.
I will no longer drool over any cycling infrastructure in Paris. It is purely for the sadistic pleasure of cafe customers to watch the gruesome results (which is surprisingly entertaining, I admit).
