I have long held that larger vehicles should have higher licensing requirements purely based on stats. We see it in the stats that large vehicles are disproportionately dangerous to other vehicles and people so licensing should catch up. We have motorcycle licenses, why don't we have SUV licenses?

This is already the case.
For sure big trucks don't pay the costs of the damage that they do to road surfaces. Road damage is proportional to the cube of speed and 4th power of axle weight. So an 80,000# semi does 4096 the damage of an 4,000# SUV, both driving the same speed.
Math:
80,000 / 5 = 16,000# per axle 4,000 /2 = 2,000# per axle
(16/2)^4 = 4,096.
