It's as unfair as complaining that an airplane company's airplanes lose a wing when their competitors often lose both wings. The standard isn't good enough and probably never will be, they've been restricted to super-well-mapped, mostly-good-weather cities without a lot of adverse real-world conditions they're going to encounter. In fact, performance may not improve, it may worsen as they expand geographically, and/or encounter "new" conditions (other robot drivers, who knows?) Humans are remarkable at coping with new conditions, machines are not.
