The utility of my car diminished significantly after disabling the radar and switching to TV. No change in terms of phantom braking (still happens but in different spots); however, due to the bad auto wipers and auto high beams the AP is pretty much unusable, especially at night (I kind of got used to the sudden dry wipes).
Considering the TV performance with AP, I am not optimistic about TV replacement for USS. They will come up with some ridiculous dependency (e.g. the rear window defogger must be on) and the functionality will not be on par with the USS.
My experience with the OTA in the past 2 years is either ambivalent (don’t care about Sonic the Hedgehog), negative (hardware is disabled; UI is harder to operate) or frustration (how hard it is to fix the wipers, high beams, album art, etc?). Don’t see any indication that will change in the future. They managed to turn OTA from asset to liability.
They will probably release some beta TV functionality for parking that halfway does some of the things USS do, disable the USS for the existing fleet and slowly fix the issues for about a year, until they lose interest and we are left with a subpar functionality but a new fart sound.
