Most humans eventually gets acclimated to their width, whether it be their own body width or it could be the vehicle they're navigating. The vehicle in question could be a 'Wide Load' truck passing through Manhattan NYC as in the video above or it could be an oil tanker in the Houston shipping channel or perhaps an overloaded passenger bus on a one lane road clinging to the side of the Himalayan Mountains with no guardrails. Once that width (and height) is established within the brain then the magic can be safely put on display as in the video above. The driver in this video is not scared or nervous, he is simply excited at the challenge presented to him.
Driving a tractor trailer within the 5 boroughs of NY and/or northern & central New Jersey HAS to take years off your life. Narrow streets, poor signage, A LOT of super aggressive (and oblivious) drivers, constant road construction, 100 year old bridges and tunnels..........and people EVERYWHERE...........day and night. It must be difficult to get experienced drivers to go into those areas.
There are height signs posted that every CDL driver needs to pay attention to, the 59th street bridge is 13”0 but when you get to LIC there’s a split where it goes down to 12’9 which he knew to avoid. But majority of overpasses around NYC are 13”0 or slightly higher depending on the area
Hate to admit it but my blood pressure would be tacked out doing this. I haul ten wide steel plate in downtown Seattle occasionally and as soon as I come off the freeway into the city my adrenaline is pumping.
