Harper repackages basic high school physics as expert insight, stating the obvious while ignoring the deeper systemic issues of road design. It is a classic example of using undeniable science to sidestep more uncomfortable conversations about infrastructure safety.

How will increased speed limit impact collisions?Added:
We're concerned, the public should be well aware of the impacts to increasing speeds. As speed increases, the amount of energy increases um by a exponential factor. So a physics shows that a speed increase from 110 to 120 is a 9% increase in energy but it leads to a 19% increase in in or increase in 19% increase in energy 9% increase in speed.
If you went from 110 to and uh 30 that would be a 40% increase in in energy. So people have to understand that when this happens because you're traveling further when you have have an accident your distance to stop increases and the impact because of the more energy you're going to have a more severe crash.
