I wish there were more regulation on the size of private vehicles, particularly in North America. It’s pretty clear at this point that what is contributing to higher pedestrian/cyclist fatalities despite better urban infrastructure is the increasing curb weight and ground clearance of automobiles. We can hope that collision-avoidance tech in newer models may reduce human-error type accidents, but at the end of the day, kinetic energy is a bitch.

I wonder how the EV transition will affect things? On the one hand, an EV would weigh more than an ICE of the same class since batteries are heavy. On the other hand, batteries are also the most expensive component by far and you need more in a larger vehicle, so from a dealer’s perspective, the margins may not necessarily grow the bigger you go like with an ICE. The sweet spot might actually be something smaller. (In fact, for me, it’s actually ebikes.)

It’s because practicing engineers (as opposed to road safety researchers, who are silo’d in academia) are obsessed with Level Of Service (LOS) for cars to the exclusion of all other concerns. Cyclists and pedestrians are a joke to them, whose safety is to be afforded lip service, at best.

Traffic engineers are people who would demolish a thriving main street to build a six-lane 55mph highway and have the utter gall to call it an “improvement.” The entire industry is fundamentally fucked up, working from incorrect premises to achieve incorrect goals.
