Apparently, the author has never arrived at a four way stop at the same time as another car.
- mbreese 11y agoAnd yet - if there are human drivers, even if 4 cars hit the intersection at the same time, eventually someone will go first. It might be comical for a few moments, but eventually things work out. With self-driving cars, you could end up in a deadlock and no one would get anywhere...
- troels 11y agoI imagine it should be trivial to work out an algorithm to break the deadlock. We have plenty of software systems, that needs to deal with similar problems.
- cornellwright 11y agoFrom other articles I've seen this is something that's already been dealt with. One of the problems they had early on was all-way stops where human drivers were so aggressive that the self driving car would never get its turn to go, instead getting skipped by humans that just went when it hesitated for an instant.
- ohitsdom 11y agoAs self-driving cars take off, they'll start to form a mesh network and communicate. This four way stop scenario is solved in an instant. And when the grid is fully automated, they'll be a huge decrease in four way stops (and any slowdown/stop inefficiencies in general).

- drunken-serval 11y agoAnd I've been deferring to the left for 10+ years... Great.
- mangeletti 11y agoExactly. The rules state that the person on the right has the right of way, yet people freeze up, then both go, then both hit the breaks, etc.
- roymurdock 11y agoBe bold and cast fear from your heart mangeletti. Software cannot be bold. I intend to conquer self driving cars at all 4-way stop signs.
- DrScump 11y ago<Driving 101. In the US, the car to the right has the right of way.> Law 101: driving laws are state-specific. Law 101(a): Maybe I'm not understanding what you are trying to say here, but for CA and taken literally, it's incorrect. See, for example, CVC $21753. http://leginfo.legislature.ca.gov/faces/codes_displayText.xhtml?lawCode=VEH&division=11.&title=&part=&chapter=3.&article=3 http://leginfo.legislature.ca.gov/faces/codes_displayText.xh....
- roymurdock 11y agoI think you've misunderstood me. I was responding specifically to the case pointed out by the OP in which 2 cars get to a stop sign at the same time. Here's the relevant CA code, and I haven't heard of a state that does it differently: 21800. (a) The driver of a vehicle approaching an intersection shall yield the right-of-way to any vehicle which has entered the intersection from a different highway. (b) (1) When two vehicles enter an intersection from different highways at the same time, the driver of the vehicle on the left shall yield the right-of-way to the vehicle on his or her immediate right, except that the driver of any vehicle on a terminating highway shall yield the right-of-way to any vehicle on the intersecting continuing highway. http://law.onecle.com/california/vehicle/21800.html http://law.onecle.com/california/vehicle/21800.html
