The average weight of a reasonably new semi is around 20k pounds without fuel which leaves 60k for cargo. Every pound the tesla weighs above 20k is a pound less cargo. Another consideration is the fact that tesla trucks won't be paying for huge amount of road wear they cause. The national average of state/federal tax on a gallon of diesel is around 65 cents. As things stand now an electric semi (just like electric cars) will be getting a free ride.

Considering that road damage is proportional to axle weight to the fourth power, I can see weight transport taxation in the near electric future...

All depends on if the cargo is volume limited or weight limited.

You don't have to solve every single problem at first even though it would of course be better.
