This is less than 2 years from now. How many vehicles, all over the world will be available to hire to go from point A to B, whether backup driver or not? Right now there is Uber, NuTonomy & Delphi with self driving vehicles for hire with backup drivers. Voyage, GM/Cruise/Lyft and Waymo sould like they will start this year as well. Does any one have a current count? Uber is supposed to have 100 Volvos. NuTonomy & Delphi have just a handful. So maybe 50-110 right now.
