I don't really believe that those AI guys are cheating. But this incorrect traffic sign shows that they're pulling some traffic sign data in from someplace. There is no way:
a) That the AI reads a car tire as a 31MPH speed limitb) That the AI would think that any US city would have a 31 MPH speed limit.
I caught this since for some reason on a recent drive through Trenton, Tennessee I didn't drive past a speed limit sign. The town is known for it's unique 31MPH speed limit. Usually locals have a 25 or 30 MPH speed limit.
Ooooh, the plot thickens. Here they flag it as 30MPH when it's 31MPH!
Whatever is going on exactly, it makes a lot of sense to do.......... almost. Except for here in the tea pot capital, Trenton, TN, USA.
Unlikely, AI can see weird stuff in images we don't expect it to see
What you see there is not a speed limit sign. It is a height limit sign.See here: https://commons.wikimedia.org/wiki/File:Zeichen_265.svg
