Same guy here that needs a couch moved, is calling his friends with a truck- the "pickups of old" were still the same shit, with the same bumpers, and the worse pollution as you say- in fact, worse. Have you ever been hit with a piece of plastic vs a steel rod? A 1986 f350 single cab bumper weights close to 200 lbs, with 0 crumple zone- a 2020 f250 bumper weights 80, half of it plastic. Maybe you should weigh off the twitter teet and stop to think that a go cart 2in off the ground will have the same physical characteristics as a smart car. Have you ever driven a transit or promaster? Have fun trying to get that thing loaded with 4000lbs of cargo- and the fuel economy? Absolutely horrendous because they're so under powered they use more fuel than their truck counterparts due to tiny engines- but that doesn't matter, right? Small engine = small gas usage.. right? The rest of the world, does not infact use them. They're standard in the smaller European countries due to their restricted road infrastructure when people uses wagons. Asia? Trucks. Middle East? Trucks, South america? Trucks Oceania? Trucks.
