I have one ordered from about a month ago. Apparently they had some complaints and have reworked the design to ensure no contact between the cover and the window. Delayed my delivery a while longer.
Don't think it has anything to do with fsd "comfort." I live in a rural area and it stays 5-10 mph under set speed despite wide open empty roads. My Honda from 30 years ago would drive at the speed I told it to, this should too!
Speed is most irritating to me. It used to drive the speed I set it at. Now I set to 65 and it drives 55-59. The auto speed is even worse, typically drives under the speed limit….
still love fsd, use it every day. But hate having to press the accelerator the entire time
