I wonder how it will handle the stop sign on the 376 on ramp in Squirrel Hill.

What makes this stop sign a challenge?

  In most places, when you merge onto a highway you have a ramp of decent length with a yield sign. You are able to get up to speed and merge safely. In this particular spot, the end of your on-ramp has a stop sign. So, you're sitting at a dead stop with 65+ mph traffic 10 ft in front of you. Things get even more complicated since you're merging into an exit ramp. You have approximately 1/4 mile of road to merge into the fast moving traffic, then immediately get over a lane otherwise you're on the exit ramp!

    Why is there a stop sigh?! Isn't that a usual merge/exit pattern?

    Wow, that is really weird to me. In Houston, on I-10, there are some on ramps with stop lights to control the amount of traffic entering but they are not always used and are turned off when freeway traffic is traveling at speeds. Additionally you still have some space to accelerate which it looks like isn't available here.

    Sadly, in Seattle, most drivers drive as though there is a stop sign at the end of every Interstate on-ramp. Not sure what causes this behavior. For a bit of humor: http://scottberkun.com/2011/help-me-teach-seattle-how-to-drive/ http://scottberkun.com/2011/help-me-teach-seattle-how-to-dri...

I'd imagine that'd be the easiest thing to automate. if (currentLocation == Squirrel Hill on ramp){ car.Stop(); } car.merge() and then it can communicate with the other autonomous vehicles anticipating a difficult merge in this location to allow the safest merge possible.

  It's worth keeping in mind for the HN crowd that "communicating with other autonomous vehicles" will require a huge leap in secure networking including government control of the car's software, basically.
