My favorite blinker scenario locally is an offramp/series of interchanges getting off a local interstate which calls for several right blinker indications in a row:

• Start on 2-lane 55mph turnpike with exit coming up on the right in ~.5 miles
• right blinker goes on as the turnpike gradually widens to 5 lanes, adding new lanes on the right every ~.1 miles - I leave the blinker on as I hug the solid white and slip into each new lane as it comes
• After .2 miles of being in the rightmost of the 5 lanes, I slip onto the exit ramp - blinker is still on
• After another .1 miles, the ramp splits and I take the right side of the fork - blinker still on
• Yet another fork after that where I stay to the right again
• Another roadway merges in on the right
• Come up on a T intersection of the off-ramp with the surface street and, you guessed it, the blinker is STILL ON, and it’s another right turn for me
• That last 90° turn is enough of a steering wheel rotation to trigger the automatic shutoff of the blinker
• Grinning like an idiot the rest of the way home, fucking glorious
