the lead poisoning would only really apply to people 50 and older, i would think, based on my assumed timespans of leaded fuel and continual exposure to it.
a lot of other countries around the world do have bells on some of their freight lines, but it seems to be primarily US import freighters, though there are domestic manufacturers outside of the US that do use bells. I hear they're relatively common in canada as well? Makes sense frankly.
the reason why mass matters is because if you have more mass, let's say twice the mass of a sedan for example, you transfer significantly more energy into the smaller vehicle, and the smaller vehicle transfers significantly less energy into the large vehicle.
go find a video of a freight training crashing into a car or something at a crossing. There's a reason freight trains don't have crumple zones.
it can be cheaper that way for a lot of reasons, you might not be in network, your insurance might not want to cover it, there might be a million other factors, often times it's just easier, and cheaper to go somewhere else, do that shit, pay out of pocket, go home, feel better, and then start working again.

mogs are cool, i don't know much about them because they seem to be primarily european, but i will probably own one someday out of curiosity, i only hear good things about them.
Personally i'm a fan of industry trucks though, tatra, oshkosh, unimog, the usual suspects. Ford can eat shit.
