But that pattern wouldn't be allowed on a stop sign, it would have to almost entirely obstruct it to work since we're so used to looking for the shape and even a hint of red, all it took to confuse the AI was a word above and below that covers a very small percent of the area. Stickers on stop signs are ubiquitous in a lot of places, so this is a fairly probable situation, whereas I've never in my life seen a stop sign that was so obstructed that I wouldn't recognize it. I'm sure someone could design a stop sign the machine could recognize and we couldn't but that's not what's on the roads and arguing about that is pointless because the amount of infrastructure you'd have to replace to get there is so massive that it's not relevant.
- WithinReason 4y agoThis was not done using random stickers, but by using stickers that specifically exploit the recognition mechanism of the car. It's like creating an optical illusion for a human to fool him into thinking it's not a stop sign.
- xypage 4y agoYeah but an optical illusion to confuse a human would have to cover most of the sign I think, and I know this isn't a random sticker but if this is possible there's no way that people don't make some and put them on signs just to mess with the cars because they can. In fact, I'm sure they'd do the same with stickers that would confuse people, it's just that there aren't any (that we know of, but considering self driving is a lot newer than people driving I'd say finding one for cars already but not people is telling on it's own) small enough that they wouldn't get immediately removed.
- WithinReason 4y agoWhy not just remove the sign if you want to mess with people?
- xypage 4y agoIf you remove a sign it gets replaced right away, if you put a sticker that barely covers it like this then it probably doesn't get taken off for weeks, if at all.
