>Source for that? I used to work in automotive assembly as a robotics engineer. Besides being well-known in the automotive industry, it doesn't take a lot of internet sleuthing to find. "In general, there are two reasons why late-model cars are much heavier than their predecessors: safety and convenience."[1] "The U.S. has a bunch of extra safety standards that the Europeans don't. For instance, in America, car makers have to design airbags to protect people who are not wearing their seatbelt. In Europe, they just assume that everyone's buckled up."[2] I think you're conflating standards and the result of those standards with your links. You can levy a bunch of requirements that drive up weight and also don't have a meaningful impact on safety. We might even agree that they requirements aren't particularly effective, but that doesn't mean the manufacturers can skirt them. Whether or not the standards work, the result is the same: heavier vehicles. >I don't know how US safety rules apply but that would be pretty stupid if cars capped to 50km/h were subject to the same requirements as highway-ready cars. The market for those vehicles in the U.S. is extremely niche, generally relegated to ATVs. So much of the U.S. is connected by highways that there's very few people who a) want/need to own a car and b) also have no need to travel on the highways. People who only want a small urban commuter will often just get a scooter or motorcycle.

  No offense, but I get the impression you’re speaking from a place of ignorance which makes it easy to latch onto pieces that confirm a preconceived bias. Even if the cars all have airbags, it doesn’t mean they can pass US crash tests. That means they can’t nearly even be offered in the US. For example, EU frontal crash tests use a deformable barrier while the US does not. Relating to the study received for your safety assessment, it says the distribution of differences overlaps with zero. That’s a red flag that you can’t make a claim that they are any didn’t different. Your claim about US commits is incorrect and less than half of the actual value in both distance and speed. Avg. speed is also not an appropriate metric. I could go on, but there’s a lot to unpack. The latter point is that I’m not convinced you actually understand the differences between US or EU car manufacturing or parts of US culture that drive some of those decisions. There’s certainly an overrepresentation of SUV and trucks as commuter vehicles but there’s also a huge portion of the population, especially in the vast rural population, who have legitimate and pragmatic reasons to these vehicles. (And that’s coming from someone who drives a small hatchback)

    > No offense, but I get the impression you’re speaking from a place of ignorance Bruh, if you're gonna make statements like this, your argument needs to be stellar to back it up. And then you go: > especially in the vast rural population The US rural population is tiny, it's less than 20%, it's the same kind of argument as “people have families” when barely any household is more than 4 people. The reason why almost 70% of people are driving an SUV or a truck has nothing to to with families (90% of which fit in a four-sitter) or the needs of rural life (that's also why pickup truck's bed has shrank so much over the past 5 decades). In fact, the growth in usage of these cars happened coincidentally to the decline of rural population and large families. Your focus on safety as the root cause is also pretty dumb, since any SUV from the 90s would fail European current safety tests anyway, despite being enormous already. > Your claim about US commits is incorrect and less than half of the actual value in both distance and speed. Please provide your sources, because it doesn't match with what I could find online. (I realize that I made a calculation mistake: it's 20 miles and an hour in average so 20mph). > Avg. speed is also not an appropriate metric. Yes it is indeed. It's not perfect, but it's still appropriate, because it means that the commute time is driven by traffic congestion, and even your car going up to max speed for a small part of your trip isn't going to save you much time.
