What you're saying is that that's kind of going to be a dead end because you can't just keep improving that route and get to fully driverless at some point, and then a driver is going to say, "This feels safe," and climb into the back, and something ugly will happen.
Što nam govoriš je kako će to na neki način biti slijepa ulica stoga što ne možeš samo poboljšavati po tom putu i doći do rješenja posve bez vozača u nekom trenutku, te će onda vozač reći: "Ovo ulijeva sigurnost" i zavaliti se u naslon, a tad će se dogoditi nešto ružno.
