Nonsense. There are multiple clear corridors that public transportation makes perfect sense for. A high-speed rail line from Fort Collins down south through Denver, to Colorado Springs, and potentially as far south as El Paso, seems obvious.

The Utah North-South corridor, as well. A line going from LA-LV-St.George-SLC area also makes enough sense. Not to mention a line connecting Tucson-Phx-Prescott-Las Vegas (potentially going to Reno as well). A Seattle-Portland train makes sense. A whole PCH line makes sense.

there's always something to complain about, isn't there?

Lmao, tell me you truck cosplay without telling me.

The vast, vast majority of construction sites don't need a dualie. Hell, half of them don't need a truck. I've seen and met numerous plumbers, electricians, and carpenters who roll up in a van. My uncle was a GC for 40 years. My other uncle was a union pipe/sprinkler fitter. My cousin is an electrician. My other cousin owns a roofing company, and my pops is an architect who regularly makes site visits. None of them owned a work truck. The only one who does own a truck is the roofer who got a Raptor for fun.

The majority of truck owners do not haul large cargo. The majority of construction workers do not bring tools requiring a bed each day. Lawn crews use trailers for their actually large equipment. With fewer and fewer exceptions each year, trucks are increasingly bloated emotional support vehicles for insecure and obnoxious turds.

While you were right in calling that an exaggeration, the only people who I've ever seen use a dualie for real work were all towing horses.

I have never seen a person with a dualie who actually hauled things. They're cosplay items. Fuel efficiency is a negative for that market segment.

I think your question carries the seeds of the answer within it.
