I tried out my automatic turn signals last night on a long highway & traffic drive, and they are simply fantastic! This is the new gold standard for turn signals. It used to annoy me that the car would only give 3 flashes and was not adjustable. Now, when you partially engage, they will flash and the rear view stays on until you are in the next lane. They are not perfected yet for exit ramps and lane forks. But they are amazing as they are.
