Having observed my 2023 Model 3 in latest FSD version:
* fail to be able to successfully enter a busy traffic circle
* fail to navigate turns correctly, threatening to hit curbs without intervention
* fail to properly handle unexpected situations such as a tractor trailer poking out into the roadway
I find it highly unlikely that any existing Tesla's will be made to be able to safely autonomously drive without significant retrofit of the hardware. If the camera + compute system can't handle a typical Boston rotary, nobody is gonna ride in these autonomously except in low traffic, simple roadway areas of the US.
