Way too often I see people signaling as they turn, not because they are trying to communicate with other road users but because it’s the law. Indicate your intent first and then take the indicated action.
And crossroads that aren't at 90 degrees. Like, you know, old cities that weren't built on a grid.
The one time i test drove a Tesla I abandoned a left turn because all the roads involved were curvy enough I couldn't get the turn signal to stay on ;)
Mind, it was just a test drive. I guess that if I practiced for years I could master the wisdom of Tesla controls.
But, as a sibling comment already mentioned: roundabouts! One of the most important indicator engagements is made crazy awkward for people who keep "walking" their hands to neutral position while the wheel is turned instead of wrestling it like some animal.
Which does make me wonder: has any carmaker started engaging turn signals from navigation? I'd imagine that this could be an amazingly subtle user interface for following a route: just don't press the veto button when the car decides to engage indicators and steer as if the indicator decision had been your own. No more following robot voice orders. An established pattern I don't know about? Tried, but turned out to be terrible? Legal uncertainty (or legal negative certainty)?
