What do you call that when you subconsciously suppress any tests or scenarios you know will break your code? Like you notice somethings kinda racey but it involves other components you don't control and so you don't do the parallel tests you probably should, that kinda thing.
Because that is exactly the bad feeling I get with Waymo never actually testing anywhere that doesn't have mm-precise maps and the all important California weather. There seems to be this implicit understanding that when you drop the thing in light snow it will just careen off the side and nobody is particularly incentivized to find that yep, that is exactly what happens.
(Even in these simulated scenarios here, you got what looks like a barren wasteland and exactly two cars)
- Retric 6y agoWaymo is opening testing in Ohio right now, so it’s going to deal with terrible weather soon enough. https://www.limaohio.com/news/438416/waymo-to-open-ohio-test-site-for-driverless-vehicles https://www.limaohio.com/news/438416/waymo-to-open-ohio-test...
- ketzo 6y agoWell, devil's advocate here, but teaching a car to drive in good weather is hard enough, and has lots of applications! It doesn't seem totally unreasonable to focus on that first?
- sippeangelo 6y agoYes, if basing your entire model on visible road markings that is broken by a light coating of crystallized water.
- ra7 6y agoNot if the roads are mapped. You have prior knowledge of exactly where the markings are even if it’s not entirely visible due to rain.
- chrisseaton 6y agoIf the road markings are visible, do you use them? Or do you ignore them and never use them since they may sometimes be covered? The former? So makes sense for an automatic system to do the same? > a light coating of crystallized water Do you mean snow?
- swsieber 6y agoOh. Personally I learned how to drive in good weather first.
- ra7 6y agoThey have been testing in snow in Michigan, rain in Washington and a bunch of other places. You just don’t see it because they’re not operating a commercial service there yet. Arizona is where bulk of their operations is currently and where they offer a commercial service, so it makes sense for them to focus on that area in their safety reports.
- kadoban 6y agoOf course they're incentivized to test and implement for other areas. Their system will be worth astronomically more if it works everywhere and if it requires less precise mapping. Why would you assume otherwise? Also, small thing but it's AZ weather, not CA.
- GhostVII 6y agoSo long as they are intentionally constraining themselves to well mapped places with good weather, what's the problem? Summer tires don't work in the snow either, but that's fine because they aren't expected to.
- reitzensteinm 6y agoEven if you require precise mapping, that's not at all a deal breaker. Google went and mapped rural Kenya to make Google Maps. Mapping wealthy cities with >1 million population for a product with vastly more revenue potential is a trivial hurdle.
- bsder 6y ago> There seems to be this implicit understanding that when you drop the thing in light snow it will just careen off the side and nobody is particularly incentivized to find that yep, that is exactly what happens. Most people from Southern states will careen off the side when dropped into light snow--I'm exaggerating, but not by a lot. If the Waymo car does nothing else short of "maintain appropriate following distance" it is already ahead of 90% of all drivers in all weather.
