To play devil's advocate...and because I'm just not that educated in the space, is this really a huge deal? If we're talking couple ms at a time delays, isn't that still vastly superior to what a human could achieve?

GC pauses can be hundreds of milliseconds. You could perhaps use a particular GC scheme that guarantees you never have more than a couple millisecond pause, but then you have lots of pauses. That might have unintended consequences as well. I'm also not sure that such GCs, like golangs, can really mathematically guarantee a minimum pause time.

I've made this argument here a few times and am always shot down, but I think its important to highlight that the airline industry has an extremely robust history of automation and HCI in critical transportation scenarios and it seems to me that all the lessons that we have learned have been chucked out the window with self-driving cars. Being able to effectively reason about what the automation is doing is such an i…

Something I do not understand: there are keys difference between automation in e.g. aircraft, and what Tesla at al are failing at, e.g., how constrained the environment is; and what the exposure is to anomalous conditions is; and what the opportunity window usually is to turn control back over to a human. The thing I don't understand is, we have a much more comparable environment in ground travel: federal highways. I…

Hard real time garbage collectors have existed for decades. Of course you can mathematically guarantee a minimum pause time given a cap on allocation rate. What's stopping you?

Cars are vastly more complex to do navigation for than planes too so we need to be even more careful when making auto autos. Plane autopilots are basically dealing with just the physical mechanics of flying the plane which while complex are quite predictable and modellable. All of the obstacle avoidance and collision avoidance takes place outside of autopilots through ATC and the routes are known and for most purpose…

Which is one reason I come back to thinking that you may see full automation in environments such as limited access highways in good weather but likely not in, say, Manhattan into the indefinite future. Unexpected things can happen on highways but a lot fewer of them and it's not like humans driving 70 mph are great at avoiding that unexpected deer or erratic driver either. ADDED: You'd actually think the manufacture…

"almost hitting pedestrian" It wasn't even close. Look at where the ped is at 12 seconds, compared to the car. It's because he stopped the turn, and straightened the vehicle that the pedestrian stopped and looked up with concern (at 13 seconds). Even if the pedestrian broke out into a full run, they wouldn't have been in any real danger. This sort of close interplay between pedestrians and cars is very common in citi…

Almost hitting is an exaggeration, but making a right turn while pedestrians have started crossing at an intersection is a 100% incorrect (and likely illegal) action. It's concerning to me that the "full self driving" car cannot successfully handle this very common everyday occurrence.
