35-40mph is where I draw the line. I've ridden in worse, and the scariest thing is to have a cross gust blow a big SUV into the bike lane right after they pass you. Drivers get caught off guard by those cross winds, and with the huge surface area that some of these big SUVs present, they get blown around fairly easily.
