Not actually as conclusive as the black/white in the original image, but I find the best spot in traffic to judge people is a roundabout.
A normal lane change can be dangerous to the driver if they don’t use the turn signal. When exiting a roundabout however the only reason to use your signal is to notify other drivers, with no benefit for yourself. So if someone does not signal there (and that is quite common) it’s a pretty good indicator about what kind of person they are. (self-centered or half-asleep)
When I was learning to drive I’d have to go through 2-3 roundabouts just to get out of the residential area I was in so it was hammered in pretty early to always use signals, but there was one roundabout that was always a pain to navigate. Two-lane roundabout, those can always be a pain to navigate but lane markings were good so if you entered the roundabout in the correct lane you’d be naturally guided to your exit.
The problem was that coming in from the nearby motorway you’d have the innermost lane signposted as the 4th exit, practically a U-turn, and the outer lane was “all other traffic”. Even better, that signage was only painted on the road itself so if there was a queue or just a car too close in front of you you’d easily miss it. Inevitably anyone taking a right turn (3rd exit, think left turn in most other places) would only realise at the last second they were being guided to the wrong exit and they’d swerve in front of you, if you were lucky they might signal for half a second first. I commuted to work by car at the time and dreaded that roundabout every trip.
The best part is if you took the next exit which you were being guided to, it led straight into another roundabout so you could make a U-turn with absolutely no risk. If you were in the wrong lane you probably weren’t familiar with the area so you wouldn’t know that was there… But then after that was a retail park so you could clearly see all the parking space and know you could turn around there anyway! Some people would rather crash than take a minute or two to turn safely.
