I was thinking stop-and-go traffic, which is murder.

Heavy load = longer stop distance = lengthier minimum safe following distance

Minimum safe following distance > 1 car length = motorists darting in front of semis

Rinse and repeat. Assuming a heavy load and ignorant motorists, there's no way to avoid constant unsafe situations. As soon as you create a new safe gap, someone slides in.

So, no. It's terrible. (And I'm not even mentioning the additional gear shifts)
