Extremely cool feat. Next try Chicago or Detroit in January guys.

Thats one of the reasons why Uber chose Pittsburgh for development. We might not get the same amount of snow as those cities but we get enough and have a variety of terrain for them to use as test cases.

Chicago and Detroit don't get all that much snow.

(Southern Michigan gets quite a lot of snow. Prevailing winds are westerly so lots of lake effect. Grand Rapids gets almost 2x the snow that Detroit gets. Cleveland also gets more snow than Detroit, lake effect from Erie)

Now that tesla has started to pretend selling autonomous cars now is making sense, the field went from research ( where researcher honestly reports shortcomings themselves) to the horrendous world of SV start up, where everything should be considered a lie until the day someone can actually buy the stuff and test for himself.

Cruise is now owned by GM, which I really doubt is going to throw something out into the market without testing very rigorously first.

I get GM cars as rentals pretty often and while they're better than Chrysler I don't have a lot of faith in their product.

Nice. It's annoying that they provide only 10x sped up video. Watching this slowed down is helpful. Notes: * There are frequent steering twitches to the left. This may be associated with passing parked cars. There are similar twitches to the right when in the left lane of a one-way street. * Crosswalk behavior when turning needs some work. The vehicle enters the intersection, then stops in the intersection before the…

At one of the red lights it comes to a complete stop then crawls forward. 0:49 Maybe because of the cars turning left. That stood out to me

I counted 30 seconds of being stuck behind the unloading van with no way to pass without crossing double yellow. I didn't notice the autonomous green light turn off though. Possibly the algorithm is, if you're stuck then certain rules become flexible.

Worth mentioning, 30 seconds would feel like an eternity inside a car.

"Level 4" means that no human intervention is required and in case of conditions going from good to bad, the car can autonomously put itself in a safe state. That was nice and clean city driving in the video clips but nothing that distinguishes it from "Level 3" (human intervention may be required within ~15 seconds or so) or even "Level 2" (human intervention may be required within seconds, current state of the art)…

I imagine a space defined by visibility, traction and road flatness. A large space of Level 0 conditions, i.e. the conditions within most humans can drive, encapsulates Level 1, i.e. cruise control, which mostly encapsulates successive levels.

The benefit of this is you notice where levels "poke through," e.g. Level 4 may work on a sunny day, but a small change in rain or road conditions could downgrade the system to Level 1. As time goes forward, the inner levels can be expected to radiate out.

EDIT: Never mind. The point of "Level 4" is it is competent in all reasonable operating domains.

Detroit may have a lot more complex situations than Grand Rapids, and even thought it gets much less snow it does get storms with several inches which is enough to cover all the lane marking and making things very messy with traction control coming on a lot. I would say they need to deploy to as many cities in as diverse conditions as possible, but that's after they master stuff like in this article.

Once they can traverse Chicago or Detroit in the winter safely then they can try Grand Rapids or Buffalo.

For the record in East Lansing we get a lot more snow than Detroit but we're pikers compared to say Holland or Grand Haven.

> The pedestrians now block the vehicle, and the vehicle blocks the bike lane

Entering the bike lane appears to be legally-required [1] behavior for a driver turning right across a bike lane in California. Entering the intersection, however, i'm not sure about.

Random side thought: How do I signal in an ambiguous situation to the car on who's going first. Like Super high traffic and I want to merge in front of them or let them go first? Currently I do that with a wave. Which is super effective on a motorcycle as people almost always say "sure we can squeeze you in here" which lets me get places way faster.
