I was answering the question: " I wonder if there will ever be legislation to have the skirts mandatory on trailers."
I answered that it makes no difference in this manual driving case nor does it make any difference in RADAR-dependent Autopilot/FSD system that Tesla has now.
To fix the manual driving issue, the driver needs to be attentive and brake a long way before closing in too near to the truck. Also, Tesla can add a driver nanny interior camera system to monitor the driver's attentiveness as requested by NTSB so that the car can be automatically impounded as needed either with Autopilot or not.
To fix the current RADAR Autopilot/FSD issue, other brands claim the need to add LIDAR. Musk is thinking to switch off from RADAR completely and go all cameras starting a few days from now in April in response to criticism from pro-LIDAR :
"Next significant release will be in April. Going with
pure vision — not even using radar. This is the way to real-world AI."
