Awesome! Now do it again and when it passes one set of parked cars on the side, have someone roll a soccer ball in front of the Tesla. Will the car assume a child will follow from in between the cars or not?

> Will the car assume a child will follow from in between the cars or not? Will most human drivers?

Should we not expect both to?

Probably is. The computer power necessary to go higher would use all the battery and take up a ton of space. If you've seen other self driving cars, they usually have no trunk because the entire thing is server racks.

Maybe this is ridiculous, but is it feasible that Tesla plans to use the SpaceX Starlink satellites to offload data for processing remotely?

Unlikely, too risky. Even the slightest glitch in the network could be disastrous. The car has to be at least smart enough to pull over and stop safely.

I would expect both to, but for me the baseline is "as good as the average human". So in that vein, not predicting a child after a ball is still better than the baseline.

Most will assume this, the correct question would be: Would most human react fast enough?

Which sensor has primacy? radar, lidar or camera? I recall it mentioned somewhere that, after a well publicized tragedy hitting the side of a white truck on a bright day, Tesla was moving to radar? And yet a lot of the cues this awesome video shows seems to be camera-based line detection etc?

The problem with that collision is that neither the radar nor the camera saw the obstacle. To the camera it looked too much like the sky as you say. To the radar it appeared to be a stationary object and so probably an overhead sign or something instead of another vehicle. Once the car gets close enough that the radar's cone only includes dangerous obstacles then it starts putting the brakes but in that case it was too late.

In general, though, the art of combining information from multiple sensors is called sensor fusion and its a fairly well understood problem. Well, sometimes even good engineers make mistakes, see Schiaparelli and the saturated Kalman filter inputs, but we have a good idea of what those mistakes can be for different schema.

EDIT: Mistyped radar as lidar, fixed.

I believe this was released as part of Tesla's Autopilot hiring announcement. More details here: https://www.tesla.com/autopilotAI Definitely someone's dream job ;) I particularly like the applicant query: "Tell us, what extraordinary work you have done?"

Two issues, first: I thought fully autonomous driving was meant to be done by now? Second, don't Tesla & SpaceX have a reputation for being a terrible place to work, with Musk expecting everyone to be working as hard (or harder) than him, and firing people in weird and capricious ways.

I've gotten the impression that the "firing people in weird and capricious ways" bit has been greatly exaggerated.

I do think anyone taking this has to expect grueling and challenging work. The job description practically demands that.

Though only(?) Tesla pretends that their adaptive cruise control is full blown self-driving.

Source? If you simply refer to it being called "autopilot", cmon that's not too serious. The word "autopilot" does not automatically mean that it is full self-driving. None of the Tesla drivers or potential Tesla buyers realistically think that it has level 5 self-driving yet. UPD: The buy page literally says: "The currently enabled features require active driver supervision and do not make the vehicle autonomous. Th…

The Model 3 Builder literally says: "Full Self-Driving Capability".

I've been driving a long time. I rarely see people hit their brakes when a ball comes out, or even slow down. My anecdotal evidence from 300,000 miles of driving says this isn't the case.

I wrote code that worked....

I like boring things.

A neural network needs to be taught this and then all cars with that training will respond correctly forever.

Every individual human would need to learn this separately from experience, which would require far more soccer balls (and children).
