To me, an “autonomous” vehicle is one I can have sole control of, not a computer.
And Germany was one of the countries that had the state take over the railroads very early on. They have no concept of having railroads in the private sector, something that was very successful in the USA until the left’s grip on power after WWII became stronger (the left being represented not only by the Democrats but also the “New Republicans” who later were colloquially known as RINOs).
To each his own. But the vehicle isn't "autonomous" if you control it.
