If a single semi stopping, or trying to stop, can jackknife, what do you think the chances of 4(!) vehicles getting stopped in a safe manner.
You've driven 4 vehicles on an interstate before? Ask someone who's pulled three different types of vehicles with different types of braking systems and find out how hard it would be to get all of them to act together. Then add one more. It's unsafe, pure and simple.
Why pick the guy going 75 mph and weaving through traffic over the guy going 75 mph in his own lane and driving safely? Because one is safe and one isn't. Pretty easy question. That's why you pull over someone trying to go down the road with too many trailers.
