The biggest mistake here is conflating Autosteer with Full Self Driving (FSD). This isn't necessarily the author's fault as Tesla uses the word Autopilot to mean Autosteer, but any Tesla owner should know this.

Either way, Autopilot and Full Self Driving are not one in the same and it's made pretty clear to the end user that autosteer is not for obeying street signs, etc. It's a simple lane-assist, cruise-control assist, and lane switcher when the turn signal is pressed (if you pay for the lesser of the upgrades).

That being said, Tesla's FSD is also not very reliable and in my own personal testing has aggressively "shot the gap" and flew over speed bumps. However, it at least is made to stop at stop signs and traffic signals and does so.
