You were in the right and controlled what you could.

I have driven very few big rigs and mostly small to medium size. From my experience they gave me more room with the larger truck than with the smaller ones and the larger ones had better braking ability than many of the small ones.

MN has been advertising the "Use both lanes during backups and take turns at the merge."

This would work great if people could use both lanes and then agree to take turns!
