There is also a 2 hour discussion with Chunk on this unprotected left turn with obstructed view. Chunk is a retired commercial pilot with strong technical background making the analysis fairly interesting. I watched the first 30 minutes.
Key point from that video for this forum is that Chunk feels the geometry of the driver side B pillar camera placement is inadaquate to remove the driver at this stop sign due to the obstruction on the left. The angle and placement of the camera, the obstruction on the left, the distance on how far to safely creep forward, and especially the high speed of the traffic all challenge FSD. For human to make the turn, the driver must lean forward past the steering wheel to get a slight glimpse of the traffic on the left. He hopes he has not shown Tesla a problem Tesla cannot solve as that is not his intent.
other points:
- responding to the question on how would he solve this given unlimited budget, his solution is to add more cameras
- since Elon tweeted to Chunk, that is most likely the reason the ADAS team has been there months ago, and returned recently
- these 6 lane unprotected left turn road design are not just in Florida, but also common in Texas
- with respect to make a right turn then make a U at the next light, he avoids that because in the 30 years he has lived there, there has been many times more accidents there than going for the left due to people running the red.
- cars regularly can go 85 mph on this stretch with some motorcycles going over 100 in the night.
- back in v9 days, FSD beta used make 4 right turns, but it just ends up at the same stop sign.
As a subset of my previous suggestion, all these left turn (and many other FSD) issues would be easily resolved if the US passed a requirement for all vehicles to have V2V transmitters - meaning a small radio or WiFi local signal sending position, speed and when available real time steering and acceleration/ braking actions.
Would likely be very cost effective in reduced accidents and help for all driver assist systems. Maybe Tesla could design/ propose this kit for other cars, to nudge whatever US agency do their taxpayer funded job properly.
