Much better music video of real self-driving: [1] This is what traffic looks like when you totally eliminate human drivers. [1] https://www.youtube.com/watch?v=zm_rlLyelQo
Reading through Tesla blogs and watching this video, my understanding is the self driving hardware is cameras and ultrasonic sensors. Does the lack of lidar not scare anyone else? Also, Out of curiosity, does anyone know how a Tesla behaves if you point ultrasonic transducers in the same frequency at it? Do they have special modulation to avoid tampering in this manner? I imagine you could confuse the car into thinki…
> Does the lack of lidar not scare anyone else? I don't think lacking lidar should be inherently scary, humans don't have lidar sensors either and they do well enough. I do hope that cheap solid state lidars do come to market to improve low visibility driving nonetheless.

What does it do on roads without any lane-markings? My country has lot's of them outside the cities.
It does two things. Holistic path planning uses the entire scene to identify the lane, not just the lane markings.[1] This is exactly how a human drives on a rural road. Once enough fleet learning data is gathered, high resolution maps will mark out the road surface to high accuracy (cm). Of course that's no good unless the car knows where it is within cm! For this Tesla uses sensor fusion with GPS, an onboard IMU (s…

Very cool demonstration (despite curious choice of music!). I did notice that the lane markings are suspiciously bright and well-painted throughout the video. Almost as if they'd been touched up by Tesla! Or maybe this area just has particularly diligent road-painting crews. In many parts of the real world you'd be lucky to get such clear lane markings throughout the journey, certainly not here in the UK or in places…
The first self-driving video came out a few days after Episode 1 of Westworld, where an a cover of this song featured prominently (I'm trying not to spoil it).
Elon confirmed on Twitter it was inspired by this. [1]
e: Added twitter thread link.
There's also the longer (3:28) video with the Paint It Black theme: https://www.tesla.com/videos/autopilot-self-driving-hardware...
That's really weird choice, who are picking these songs? :) I can't imagine they've licensed the music either... I guess next up is the "Highway to Hell" video
There seem to be some issues. E.g. it recognizes the joggers (0:55) as obstacles even though they're obviously (to a human) on the sidewalk. And when taking a right turn (1:01) it mistakes a hydrant and a parked car in a parking bay on the other side for an obstacle and stops for a moment before noticing that they're not actually in its lane. I think a polite driver may have slowed down gradually to not startle the j…
Does this new Telsa autopilot use stereo cameras? Would stereo camera help to have a better 3D vision? Or is a video stream enough to get the 3D data. From the video it looks like lane detection and 2D object recognition. It might use a structure-from-motion (SfM) running on CUDA to get a 3D point cloud out of the 8 cams. Does someone know more about how their new auto pilot works?
Stereo might require some level of calibration to account for camera alignment, maybe they want to avoid that? I would think that implementing stereo would be fairly cheap both computationally and in hardware- if they can get by this well without it, they could pare the stereo computations down to a few frames per second, on specific objects in the scene. Maybe a future update will add binocular cameras in the dash, but they are pretty confident about their current hardware.
A longer Tesla demo video with no cuts: [1] This one is at a consistent speed, about 3x normal, and it's worth playing at 1/3 speed to see what's happening. No freeway driving; it's driving around the Page Mill Road / Los Altos Hills area. This video shows an ahead view and three of the vehicle's cameras with their annotations. The system puts rectangular 2D boxes around things it recognizes. Road centerline recognit…

The car might have been playing on the safe side. If you look at the joggers carefully, only the left one is marked as an "in-path object", the other one has just an "object" box. They could probably tune down the collision prediction algorithm just a little bit, but that has to be done very carefully .
Why bother, err on the side of caution with pedestrians. The driver is already benefiting from auto pilot, a minor delay due to safety of other road users would be acceptable to most.

Is there an easy way to play a Vimeo video at 1/3 speed?
