I disgree.
ASS will happen.
Granted the timeline is never right, they still actually do what they say they will.
In fact they just updated the Tesla Vision USS page and added Park Assist as available and still say the other 3 missing features are coming. If they were never coming, they would have changed this page when they did the update. The more wrong info for longer time, the worse it would be if they dont do it... I think they will eventually.
It has to work, if for nothing more than to advertise Tesla's S3XY ASS
