I have travelled in my MYLR twice at night to Denver airport and using cruise control or AP is impossible because of the constant phantom braking (about 5 of them within 3 mile stretch). I can clearly see why it's happening - part of the highway stretch goes under bridges and highway changes grade, so large highway signs appear at the highway level and the "smart Tesla Vision" thinks it is an obstacle, while my human brain can process that same image much better. Highway is clearly marked and no traffic, conditions are perfect.
Should be very simple to adjust software to include simple constant speed cruise control. You would think.
