2021 Tesla Model S — wireless CarPlay drops at the same intersection — Austin / buyer question

Wireless CarPlay is reliable almost everywhere but disconnects at the same intersection on my commute. Does consistent location point strongly to RF interference, and what would you test to confirm? I am in Austin. I am trying not to assume the first explanation I see online.

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2021 Tesla Model S charge sessions. Then you'll know the next fork. Post the numbers (or the code) and people can get more specific. I already checked the easy fluid levels.

I'd treat 12V warnings as a no-ignore. On the 2021 Tesla Model S, I'd get the 12V/DC-DC side checked even if the traction pack looks fine. That's where I'd start. On “wireless carplay drops at the same intersection,” that was the fork that mattered for me. I'd want a dollar figure or a measured spec, not 'should be fine.' If your situation is the opposite, ignore me. I'm in no rush to be a hero on it.
