Just tested it for lunch. Initial observations:
1) Too much information has been pushed to the outer edges of the IC. Speedometer is high enough you can’t see it unless steering wheel was readjusted. Directional gear indicator pushed to right, easily obscured when the steering wheel isn’t “straight and level” especially when say you’ve pulled into a parking lot, and are now pulling out, needing to confirm direction of travel.
2) Overload of information – The toy car in the center of the UI is constantly updating with the sensor packages understanding of the real world. Means that it is constantly changing and showing you appearing and disappearing lines, other cars, angles, errors such as reflections from other cars chromes causing CCD lines, and the jelly sensor lines that indicate how far the car thinks it is at this moment from the car to your left, the curb, the bushes and hedges on the curb, the passing streetlamps, etc.
3) The cruise control is now digital, as is speedometer. This requires you to do math and make predictions about what will happen when engaging, disengaging, or reengaging the control. Before, I could assure that the dotted line aligned with the arrow, which would be above or below my current blue speed. The next action the computer would take was obvious.
4) It’s easy for the car to get confused, and it’s not gentle about its decisions. After entering the 520, facing away from the sun at the hour, the car couldn’t decide what to do about a slightly wider than normal lane. It literally shot the steering back and forth as it hunted from edge to edge, like a teenage driver losing control. The system also didn’t want to relinquish control to me, as I thought overriding it with manual pressure on the wheel would cancel it’s erratic behavior, instead it was a wrestling match until I hit the brakes on the freeway, further destabilizing my mass. Needless to say, the other cars on the highway were giving me a wide berth by this point.
