It's far from clear, in practice, if they're actually doing this. If they have, it would have to be fairly recent, because the list of "Oh, yeah, Autopilot always screws up at this highway split..." is more or less endless.
GM's Supercruise relies on fairly solid maps of the areas of operation (mostly limited access highways), so it has an understanding of "what should be there" it can work off and it seems to handle the mapped areas competently.
But the problem here is that the learning requires humans taking over, and telling the automation, "No, you're wrong." And then being able to distill that into something useful for other cars - because the human who took over may not have really done the correct thing, just the "Oh FFS, this car is being stupid, no, THAT lane!" thing.
And FSD doesn't get that kind of feedback anyway. It's only with a human in the loop that you can learn from how humans handle stuff.
It's a QA department. If there is a failure hot spot, then take a bunch of known "good" QA drivers through that area. Assign strong weight to their performance/route/etc.
It's interesting reading through all this, I can see a review procedure checklist:
- show me how you take hotspot information into account
- show me how your QA department helps direct the software
- show me how your software handles the following known scenarios (kids, deer, trains, deer weather)
- show me how you communicate uncertainty and requests for help from the driver
- show me if there is plans for a central monitoring/manual takeover service
- show me how it handles construction
Also, construction absolutely needs to evolve convergently with self driving. Cones are... ok, but some of those people leaning on shovels need to update systems with information on what is being worked on and what is cordoned off.
No. If the car cannot handle random obstructions and diversions without external data, it cannot be allowed on the road.
Construction is often enough planned ahead of time, but crashes happen, will continue to happen, and if a SDC can't handle being routed around a crash scene without someone having updated some cloud somewhere, it shouldn't be allowed to drive.
First responders need to deal with the accident, not be focused on uploading details of the routing around the crash before they can trust other cars to not blindly drive into the crash scene because it was stationary and not on a map.
And if you can handle that on-car, which I consider a hard requirement, then why not simply use that logic for all the cases involving detours and lane closures?
Doing so ahead of time for planned construction is not a big ask.
"And if you can handle that on-car, which I consider a hard requirement, then why not simply use that logic for all the cases involving detours and lane closures?"
You're making the same mistake Musk made when insisting that the car be able to navigate regardless of location or connectivity. Ignoring the ability of networking/radio broadcast/internet databases to provide vastly more deep information pools is a big mistake.
I guess I sort of assumed that Tesla would do three things:
- Record the IRL decisions of 100k drivers.
- Running FSD in the background, compare FSD decisions with those IRL decisions. Forward all deltas to the mothership for further analysis.
- Some kind of boid, herd behavior. If all the other cars drive around the monorail column, or going one direction on a one way roadway, to follow suit.
To your point, there should probably also be some sort of geolocated decision memory. eg When at this intersection, remember that X times we ultimately did this action.
The FSD could then infer that no other cars passed thru meridians, planters, and columns. It could infer that only busses travel in restricted lanes. It could infer that all traffic on a one-way road goes one way.
And if FSD remembered its own decision every prior time, it could reconfirm its current decision.
In other words, it could learn from every other vehicle and its own history.
Routes people drive frequently are much more optimized: knowledge of specific road conditions like potholes, undulations, sight lines, etc.
I would like to have centrally curated AI programs for routes rather than a solve-everything adhoc program like Tesla is doing.
However, the adhoc/memoryless model will still work ok on highway miles I would guess.
What I really want is extremely safe highway driving more than automated a trip to Taco Bell.
I personally think Tesla is doing ...ok. The beta 9 is marginally better than the beta 8 from the youtubes I've seen. Neither are ready for primetime, but both are impressive technical demonstrations.
If they did a full-from-scratch about three or four years ago then this is frankly pretty amazing.
Of course with Tesla you have the fanboys (he is the technogod of the future!) and the rabid haters (someone equated him with Donald Trump, please).
A basic uncertainty lookup map would probably be a good thing. How many tesla drivers took control in this area/section? What is the reported certainties by the software for this area/section?
It's all a black box, google's geofencing, Tesla, once-upon-a-time Uber, GM supercruise, etc.
A twitter account listing failures is meaningless without the grand scheme of statistics and success rates. A Twitter account of human failures would be even scarier.
