Well the other day I squeezed my canti's in a blind panic to avoid a right hook and both wheels locked up and I was sliding to my doom. Luckily I was able to release the brakes and regain traction just in time to avoid a spill, and my speed had slowed enough to avoid the right hook as well. I don't know how you can stop any faster than stopping your wheels from rotating. My cantilever brakes had no problem doing that.
