Or how about a pedestrian or bike running across the street to catch the last seconds of the walk sign?
I'm all for autonomous driving on the highway where things are somewhat more uniform and repeatable.
But AD for local, city driving that has thousands of more unpredictable events/situations? Never going to happen. The google examples are extremely controlled, slow moving experiments over the same small set of roads. I would never call that "AD".
Also, all this virtual mapping of highways? That's all great to understand the static or marginally slow changing nature of the highways... that does NOTHING for the other 95% -- the other traffic on the highway when I'm on it. They're really separate problems. Tesla can collect billions of miles of data on these highways to get a really good idea of the landscape. Doesn't do me a damn bit of good when that pickup truck cuts me off because he didn't see me in the rear view mirror.
Just curious: what are people imagining that autopilot is going to do at traffic lights? Let's hand-wave away the reliable red-light
detection problem and focus on where, exactly, to stop: some lights are immediately above the entrance to the intersection, some
hanging over the middle, some at the far edge. Sense both the light and the "limit line" on the road? What if the limit line is worn
away, or obscured by water or snow? One can, again, wave the fleet learning magic wand at this, but what are cars supposed to do
as they approach (thus far) "unknown" red lights? Perhaps a new AP behavior is required that allows it to convey "I detect something
you, the driver, need to react to but I don't have enough information (yet) to handle it myself." In order to be useful it would need to be
more specific than a generic "take over immediately -- I'm giving up" like it does today.
At this point, I think all that is being proposed is the car stop at traffic lights and stop signs, then wait for the driver to tell it to go.
I might buy that if the Teslas stopping at the light were always the first in line, but they're not. So there will actually be a blurry regionWhen you have multiple cars detecting a red light and stopping at a specific point ... [emphasis added]
Huh? Come again?If the car is close enough to detect a light changing from green to yellow, will it be too close to safely stop
Huh? Come again?
Roger, you seem to be implying this is a difficult problem, when it's already been solved by Google and others.Just curious: what are people imagining that autopilot is going to do at traffic lights? Let's hand-wave away the reliable red-light

The argument that "I'm not smart enough to think of a solution to this outlier problem." does not mean that the problem is not easily solvable. And the emphasis on perfection is misplaced -- the system has to be only ~10x better than humans to be viable, a rather low bar. Remind me how many people will die in traffic accidents and how many more will be injured even with a 10x better system. This is not going to be all that difficult (technologically). What's going to be disturbing to people is that its failure modes are going to be different, strange and unfamiliar; so we'll ask how the system could be so stupid rather than being impressed that it is so much safer overall.
Well, exactly. You don't see this as a major obstacle, sucky as it may be?What's going to be disturbing to people is that its failure modes are going to be different, strange and unfamiliar; so we'll ask how the system could be so stupid rather than being impressed that it is so much safer overall.
I'm pretty sure any responsible person at Google, or others, would agree with me that this is, at best, a gross overstatement.it's already been solved by Google and others
When identifying red light, stop at crosswalk or stopping line. If line is not visible or available, stop at intersection extents derived from sidewalks, traffic, etc. If all else fails, warn the user, log the event.
Well, you must consider Elon an irresponsible physicist because he's called autonomous driving an essentially solved problem. And, Google's already been driving for millions of miles under city conditions, with it's car stopping at both stop signs and stop lights. So, I'm not sure why you're unnecessarily skeptical of what's being done today. BTW, I'm also an engineer. The situation you outlined is not what I'd personally consider one of the more difficult problems. It's essentially a static image/object recognition problem. I think the more difficult ones will be dynamic, such as how to deal with road crews and or traffic diversions or someone waving a traffic baton.I'm pretty sure any responsible person at Google, or others, would agree with me that this is, at best, a gross overstatement.
Worked on? Sure. Impressive progress made? Absolutely. Solved? Not even close.
And I think the truly difficult problem is dealing with human predators. How do you stop nasties from waving a "traffic baton" at potential victims and having autonomous vehicles deliver them up on a platter? Yes, there are various mitigation techniques, but I imagine people are pretty clever when it comes to outwitting autonomous systems. This will scare people, no matter how much cheaper and generally safer the systems might be.I think the more difficult ones will be dynamic, such as how to deal with road crews and or traffic diversions or someone waving a traffic baton.
The obsession with full autonomy baffles me. Having said that, Tesla for now has the edge on semi-autonomous features. I prefer to drive my cars, I do not mind if extra safety features keep me out of trouble.
I'd be the first to observe that Elon can be a tad overly optimistic, and maybe even prone to occasional hyperbole? Wow, what an honor!Well, you must consider Elon an irresponsible physicist because he's called autonomous driving an essentially solved problem.
See, I think you either hit the nail on the head or just missed it.They've also been promising us "AI" since the 80's and where is that today? Nowhere really unless you're talking about playing chess or playing Jeopardy. AP is really not much different than AI.
