For at least the last two decades people (almost always male) have been tinkering with a wide variety of designs of self-driving cars that they have been dreaming of starting at least two decades earlier. Tinkering continues to be a very challenging pursuit. Finally, in early 2020 there was a modest step forward, in the form of an autonomous grocery delivery vehicle from a low-profile company named Nuro that met the requirements of the National Highway Traffic Safety Administration. But it will take a lot of time before there will be vehicles with performance and creature comforts similar to cars driven by human beings. Perhaps those vehicles will initially be permitted only on freeways or well-defined streets and roads.
