I suspect you’ve never been on the two lane portions of the Autobahn, when a truck pulls out of the line of trucks going up the hill at about 30 miles an hour so it can pass them doing 40 miles an hour. Good brakes are a necessity.
It’s also fun as you pass the long line to note what countries are represented. More Eastern European trucks than you see Mexican cars in Dallas.
Very few of those are real long-haul truck trips by North American standards. The U.S. and Europe have a comparable population, but the U.S. is about 2.5 times larger than Europe. Texas alone is larger than France.
