It's amazing how many "basics" Tesla is missing with the statement that their cars have all the tech to be fully self driving. I have an Infiniti QX80 with the surround camera system, lane stay, and collision warning system. Unlike Tesla, they've not gone as far as to implement an autopilot feature and from what I can tell, for good reason. In the less than a year I've owned it, the side warning collision sensor / camera combination have falsely identified phantom threats due to road dust and debris and entirely missed real threats. The sensors simply don't have a self cleaning mechanism like our eyes which is one fairly obvious problem that's lead to a few issues with my QX80. In looking through Tesla's marketing white papers and what-not I see no mention of how they keep their sensor system clean. It seems like that should be a pretty basic concern.
