This has always had me wondering about the viability of self driving: what's it going to be like in different countries? Not only are there different signs, different line marking & colours, & different widths. Cars are different: not all models are sold equally throughout the world. People are different: through their clothing, height and build. But the really big difference is that not everyone drives on the RHS... The article lists left turns as a problem, whereas on a LHS road system, right hand turns will be the problem. In NZ (a LHS system), I've heard that turning right across traffic has priority over oncoming traffic. In Melbourne, VIC Australia (also LHS), right turns are made from the left most lane because of trams lines. I'm sure there are loads of other issues specific to other geographies. To me, this never ending self driving experiment screams out that the wrong solution is being pursued. (That doesn't imply that I know what they should be using as a solution)
