I tried Cruise in Austin, and it was nothing more than a curiosity. What should have been a ten minute ride took almost forty minutes because the car took a circuitous route with lots of backtracking, presumably because the cars were programmed to stay away from certain intersections and avoid left turns. It was my first time in a self-driving car, so the cool factor was definitely there, but it was far from being a real product.
Not in any meaningful way though. It was limited to only night time and select riders for most people to even notice.
