As the European Union and the US try to negotiate a satisfactory resolution to the trade war President Trump started last year, a new complication has emerged. It seems the American auto industry is not happy about pending changes to EU vehicle regulations that could make it impossible for Detroit to export its full-size pickups across the Atlantic. Restricting the flow of F-150s to the continent “could breach the spirit of the trade deal,” according to US negotiators, the Financial Times reported this morning.
No, I won’t take your word for it
Bringing a new vehicle to market is a rather different process in the EU than in the US. Here, the National Highway Traffic Safety Administration practices something called self-certification. Essentially, an OEM tells NHTSA that its new car or truck complies with all the relevant federal motor vehicle safety statutes, then NHTSA takes that company at its word and the car goes on sale. Should that vehicle later turn out to have a defect, NHTSA can order a recall to remedy it. But there’s no pre-approval process by the government before sales can begin.
As you might imagine, self-certification is great for companies but less great for consumer safety.
The EU (and China) have a different system: type approval. Before being allowed to market a new vehicle in Europe, an automaker has to satisfy regulators in at least one EU country that its new vehicle does, in fact, conform to the relevant regulations. This is either done directly by a national type-approval authority or subcontracted out to specialist engineering firms. Either way, it means there are independent checks to ensure that the new model doesn’t pollute too much, that the safety and advanced driver assistance systems are validated for local use, and so on. And with the shift to software-defined vehicles and regular over-the-air updates, this will become an ongoing process rather than a one-off.

That's a pretty rich claim given a 60 year-old tariff on "light trucks" known as the "Chicken Tax" pretty much keeps Europe (and Japan, and Korea) from exporting pickups, non-passenger vans, and truck-type SUVs to the United States.
This is one of the big reasons that you can't buy a Toyota Hilux in the U.S.
I really appreciate the article pointing this out. Almost nobody in the US understands just how much of our built environment: roads, setbacks, elevator size, double-loaded corridor/single stair hotels/multi-family apartments/condos, etc. are determined by fire departments. These fire departments are basically making these decisions on vibes, and suffer from the same "big truck" mentality that F-150/Silverado/Ram buyers do.
Our fire trucks have to be BIG to carry a BIG ladder and LOTS of water and ALL our equipment. Nevermind that most of that is wasted since fire departments spend far more time responding to car accidents than structure fires. Many of of those accidents are at least partially caused and typically exacerbated by excessive speed, since nobody drives the speed limit because roads are so wide and distances between things so far (building setbacks and parking requirements) that it tricks the mind into thinking we aren't going fast enough. It's utterly absurd to send a 60k-80k lbs, multi-million dollar articulated ladder truck to respond to car accidents, but our fire departments do it routinely. The need to get to the scene FAST in that massive truck drives the requirements for wider streets which themselves encourage unsafe driving.
