Sure, but your original post assumed he took the more dangerous route. The interstate through the tunnel is no picnic either, and I'd argue it's a tossup whether going through there with all of the cars and other trucks is actually safer than Loveland.

You made an assumption based on experience you don't have that was critical of someone who does this for a living -- in fact, suggesting that the choice made by said person should carry a penalty! That is why you're seeing downvotes.

To be fair, downvotes are common when you call for legislation from an apparent basis of ignorance, as you did. They shouldn't be taken personally, but simply as an indication that your advice isn't considered especially relevant or helpful. Most of us have been there at one time or another ("There oughtta be a law...")

There is no way to avoid steep grades, but the pass he took is much more difficult to drive than taking the Eisenhower tunnel due to sharp turns. It can be stressful in a car, I can't imagine doing that in a semi.
