I have a Model 3 with FSD. I was accepted into the Beta program and have no strikes. FSD appears and works on rural roads but as soon as I go onto a limited access highway or Interstate, it disengages a disappears. I’ve chatted with Tesla support and they have no answer and gave me an email address to write to. I wrote to that adress, explained the situation and ….crickets. Is there some sort of a setting I’m missing? Does anyone have any idea why I have no FSD on highways?
