In California (and most places I've lived), this is actually legal. To complete the turn, you first enter the intersection while the light is green, then wait for traffic to clear. If it only clears after the light turns red, you're still in the right - because only when you fully entered the intersection (on the green light) is considered. See here: https://patch.com/california/sanbruno/ask-a-cop-should-i-pul... Of…

In my country there is very specific provision along the lines "it is illegal to enter intersection if an obstacle would force a stop in intersection and block traffic" which means that in a "turn left or go straight" lane you enter intersection and cannot turn left due to traffic and block traffic for cars going straight making that technically illegal. Human drivers, of course, do this all the time.

Are you sure that moving, oncoming traffic is seen as an obstacle under that definition?

The real trick against gridlock is to equate the switch to green not as "go", but as "go, once the previous wave has cleared the intersection". The "don't enter before there is room for your car on the far side" is only an optimization on top of that.

I also noticed that it was driving 25... I assumed that was 25 km/hr, which is pretty darned slow (15mph) even on snowy city streets. However, it could be that they're running the car in US mph instead?

I think it's 25km/h but those streets are pretty narrow and filled with pedestrians. Normal speed limits on those streets is 30km/h so driving between 20 and 30 seems right.

The video should be watched at 0.25 speed to get the realistic impression.

I'd be impressed if I see a self-driving car making a left turn in a crowded junction without a specific left-turn signal at LA. The only way to turn left in such roads is to make an illegal turn after the signal just becomes red. I wonder how the self-driving car would do in such a situation.

You are allowed to enter the intersection on yellow in California.

21452. (a) A driver facing a steady circular yellow or yellow arrow signal is, by that signal, warned that the related green movement is ending or that a red indication will be shown immediately thereafter.

But CA law also says you can't enter an intersection without having clearance to vacate it. In other words, if the cross street itself is backed up such that its traffic backs up or into that intersection and prevents you clearing the intersection as you complete the turn, you violate the "anti gridlock" law.

Most jurisdictions do not consider it blocking the box if you enter the intersection to turn and it turns red after. They consider it blocking the box if you enter with the intention of going straight while it is not clear to do so.

This is the case for NY state, see VTL 1175: http://www.safeny.ny.gov/rowa-vt.htm

I'd love for it to be true, but it's tough to believe that's real. There's one point where a pedestrian is standing in the snow on the road just to the side of where the car would pass: https://youtu.be/Bx08yRsR9ow?t=35s Wouldn't any pedestrian detection decide the person in the road has priority and stop and let them cross? It isn't capable of reading a person's intention to stand there vs. cross or not. The title c…

I thought 1:50 was a lot more concerning: https://www.youtube.com/watch?v=Bx08yRsR9ow&feature=youtu.be... That pedestrian is already in the street and they momentarily stutter then pass the pedestrian with very little room. That and the way the steering seems super sensitive to various snow remainders on the side of the street. It's almost as if it's controlling for its position relative to the snow instead of pickin…

>That and the way the steering seems super sensitive to various snow remainders on the side of the street.

Yes, I also noticed it, it seems like there are continuous micro (and not so micro) corrections on the steering wheel, with such behaviour the passenger (besides the driver that has some more chances, being attentive to the road, to not get it) is likely subject to get car-sickness.

In situations in which my country has that same provision, it does not treat moving traffic that crosses your path as an "obstacle", so if you're turning across traffic, you're allowed to enter the intersection and wait there. It might be worth double-checking whether your country has a similar subtlety.

If anyone was going to focus on making sure their self-driving car could drive in snow, it'd be the Russians. Mind you, self-driving when snow has coated all your landmarks is definitely impressive, but the title made me think it'd be driving in snow . Which it isn't. The roads are, what we'd call in Chicago, "clear". The car is not driving in/on snow or ice in this scenario, which is something I do regularly every w…

Canadian perspective: This is very clear. Much more challenging is something like a multi-lane highway where the road markings have completely disappeared under snow. I'll be impressed when it can drive from Hope into the BC interior in winter in conditions that a human driver can handle with winter tires and possibly studs, but no need for chains. https://www.google.com/search?client=ubuntu&channel=fs&q=coq...

Accurate GPS and a well mapped area can give the car a precise road lane when snow is present.
