That’s leaving the territory of what most people have ready access to.

The poser referred to a “6,500lb truck” vs “19-tonne Renault Midlum cargo truck” used in that attack.

it is fairly trivial to get access to a medium or large panel truck, either by theft, or by simply getting a CDL.

the 9/11 attackers went though flight school to be able to hijack planes. meanwhile getting a CDL is like $6k for out of state, $2k for in state, and ~$400 if you can demonstrate need / poverty. the classes are readily available at any community college, and can be done by anyone who can drive, basically.

The difference between things that can happen through inattention vs a drunk person might do while really pissed vs things that require significant preparation has major implications for how often they occur.

Vehicles are used to kill a great number of people per year, but it’s really unusual to find someone who actually killed 50+ people through a vehicle alone. Meanwhile there’s significantly more people who used bombs to reach those numbers, despite how much more difficult it is to access significant quantities of explosives.
