I'm in California. We regularly drive from LA to Idyllwild and there's about a ten minute stretch of 243 where the Lucid goes silent (no Sirius, no Tidal) because there's no cell service. It takes a long time to reacquire even when our phones come back online. Just roll down the windows and listen to the birdies I guess.
A satellite antenna seems like a reasonable thing to expect at this market point, but if I could only ask for five five things to be improved on the car, I don't think this would make the list. It's not enough of a problem.
