Copying form an old comment of mine:
- Yielding to an emergency vehicle with sirens on.
- Moving backwards to a safe and large enough spot when the route is too narrow to fit self-driving car and oncoming huge lorry (and there is no line marking the limit between road and ravine).
- Upon instructions from authority, recognize that the highway is closed due to an accident and, no matter what the driving code says, you actually have to make a U-turn on the highway and follow the crowd. Alternatively, just take that route (yes, the one with the large no-entry sign at the beginning) or that narrow path in the wood (yes, it exists, even if Google Maps isn't aware of it). At the bare minimum, park yourself off the road and let the others move on.
- Verify whether a queue is forming behind you. Listen to the honkers, they may be right. When you are an obstacle to the most part of traffic, moving to the side and letting others pass from time to time is sincerely appreciated.
- tyingq 10y agoOne I thought of when I encountered it the other day... Driving through a red light when it's obvious something's gone wrong with the traffic signal, and it's stuck on red. Harder than it seems at first, because other drivers at the intersection seem to make up the rules interactively, with you, via facial expressions and hand waving. There's also a fair amount of variables, like looking sideways to see if the cross traffic is also stuck on red or not.
- Eridrus 10y agoA broken traffic light seems no different than a 4 way stop once you've realised it's broken, and I'm pretty sure Waymo can handle those already.
- tyingq 10y agoIn my experience it's not the same, unless it's stuck red all four directions, and all the drivers understand that.
- sbov 10y agoIn California most lights have sensors, and the sensors themselves can break/not be properly calibrated. When you happen across this that means is certain lights will always be green, and others will always be red. It's mostly a problem with motorcycles, and I've had to go through my fair share of red lights late at night when no one was around, but I've also (rarely) had a problem with a car.
- 3chelon 10y ago- Moving backwards to a safe and large enough spot when the route is too narrow to fit self-driving car and oncoming huge lorry (and there is no line marking the limit between road and ravine). Surely you're missing the point? With V2V comms there will never be a need to go backwards. All vehicle trajectories become 100% predictable (mechanical failure aside). The problem of massive trucks on narrow country roads (which we have a lot of in the UK) is solved by simple forward planning. Hell, the trucks could get even bigger, so long as there are passing places.
- greedo 10y agoAutonomous vehicles can't rely upon V2V comms. There are far too many ways for such comms to degrade.
- 3chelon 10y agoThis kind of problem has long been solved in the mobile comms world by strong ECC codes and robust modems and channel coding algorithms. We routinely send autonomous vehicles into interplanetary space so I can't see that linking vehicles on a road is going to be a major blocker. Especially if they're on a redundant mesh network, or a smart highway.
- brokenmachine 10y agoNot a lot of cross traffic in interplanetary space though... Maybe the odd supernova.
- jcranmer 10y agoExcept the cases where you're likely to meet a large vehicle on a one-way road are most likely to be in extreme rural situations, where cell-phone coverage is far from guaranteed. And if you expect you can force non-connected cars to not exist on rural roads sometime this century, you are delusional.
