It still strikes me why so many people are still against a future with self driving cars. Sure, people throughout history are scared of change & new tech. But if you look at this video and compare the amount of stuff the camera catches AND processes, with the things you are seeing & processing, it's really hard for me to see me being better at it than a computer. The reality of driving (as a human) is that most of it…

I'd suggest reading the NTSB report on the pedestrian killed by Uber's "self-driving" vehicle [0].

The vehicle misclassified Elaine Herzberg so many times in the seconds leading up to taking her out at 40 mph - its clear to me that none of this is ready for public use.

We are so normalised to vehicular violence. This would never be allowed in any other sector, say healthcare for instance.

Much faster than a human would react. Acutely focused humans generally take at least 1 second to hit the brakes in an emergency. Longer if distracted or tired[1]. [1]: https://www.researchgate.net/publication/233039156_Brake_Rea...

Braking is slowed by the limitations of nerve conduction down to the legs. You can swerve away from danger with faster reaction time.

The same nerve conduction latency exists for your arms. The computer will beat you every time.

The dancing cars were fixed several months ago in an update. The computer used to just recognize cars, and then align them according to the lanes it sees. At a stoplight it when it had trouble seeing the lanes clearly the cars would rapidly change orientation. Since they updated the neural net to also recognize the vehicle orientations the dancing has stopped. I have seen a lane change cancel recently, a couple weeks…

Dancing isn’t completely gone - especially with large trucks.

I'm pretty sure the truck thing is because images aren't stitched yet. That's coming in an update.

The prudent thing to do there, would be to exercise prudence. Not announce to investors and the public ever more grandiose targets after each miss. As it is we're on about Autonomous Driving Promise Mk IV from Musk, "fully autonomous, coast to coast, by the end of 2020". (That's after 2018 was missed. Which was after 2016 was missed.)

> Not announce to investors and the public ever more grandiose targets after each miss. Those poor investors are really taking it on the chin today because of those overly optimistic software projections!

A massive short-squeeze/bitcoin-like retail bubble is certainly not indicative of the strength of the company. Look at the last earnings report, it wasn't impressive for a growth company.

Is someone else worried that the vision is not 180 view in the front ?

At 22 seconds at the stop sign, after the first car drives past what if theres a car that breaks the stop sign and ends up ramming into the tesla (as a human sometimes you anticipate this by seeing that the car is not decelerating as it is approaching the stop sign)

I've only seen autopilot examples in places with uniformed and fairly good infrastructure. Self driving even in the near future will be a toy for the rich and geographically privileged.

That should trickle down during time, but the fact that a self driving car is still a car won't. We need better and efficient trasport and self driving cars won't chage that very much.

There's no evidence that computers are any better at driving than humans, and there is no evidence that this generation of machine learning will be able to tackle this problem sufficiently. All signs point to driving requiring an understanding of what's going on around you, which this generation of ML does not provide. On the other hand, there is a lot of hype and promises being made without the results to back them…

Searching "dash cams" on Youtube says otherwise.

Isn’t there already a mounting amount of statistics of accidents of self driving cars vs manual ones and the difference is night and day that the self driving ones are statistically safer?

The problem is the datasets are incompatible. Tesla's numbers are very impressive until you realize that it will currently only engage in scenarios which are less prone to accidents across the board.

As the number of situations where self-driving kicks in increases to include more complex environments, it's likely the numbers will shift.

The jitter artifacts could be removed by applying some kind of temporal consistency constraints on the network predictions. But such an approach will also definitely introduce a lot of edge cases where a sudden change is actually ignored due to enforcement of the constraint. An adaptive consistency parameter could probably work better, but it's non-trivial to have a meta-algorithm to figure out the paramter.
