Most cars and trucks (maybe all?) are designed with specific HP and towing or cargo capacities. Some have more HP and can be driven faster than other automobiles. But just because yours has more HP and allows you to zip right into the fast traffic, it does not mean that others who drive slower vehicles with a great deal less HP than yours are prohibited from driving on the same roads.Sorry, I’m not sure I understand your question or your point.
It is irrelevant what other drivers should or shouldn’t do. The fact remains that if you do not have a powerful enough tow rig, with a short on ramp, it can make for a dangerous experience. That was the point I was saying from the start when the question was raised about if one really needs the power of these modern pickup trucks. When you are towing in a less populated area, with adequate runways, sure, you don’t need it. But I can tell you from my towing experience on the East Coast (and mostly in the Maryland to Maine region) we have short on ramps, often combined with inclines, populated roads, and impatient drivers that if you are towing, you better have some power…
The big rigs (large cargo trucks) that carry great loads move to the rightmost lane that are designed for the slower vehicles driving up a large incline. These trucks have large engines with lots of HP, but if carrying a heavy load they can only move up the incline at a very slow speed.
In relation to older or smaller trucks that don't produce great HP, they still have specific towing capacities. Towing capacity is determined by the vehicle's power to weight ratio. If I were to tow a trailer (loaded) that surpasses the towing capacity of the vehicle, then I am asking for trouble.
