Uncomfortable Recumbent

That when you're riding a regularly designed bicycle a rider on a recumbent bike will sneak up on your right side without announcing himself (or herself). While the rider is hiding in your blind spot - back and to the right - you'll drift to the right and suddenly tumble onto the rider and his freakish bike causing a limb-ripping and life-altering crash that will mangle you and your bike horribly.
