My favorite blinker scenario locally is this really disgusting offramp/series of interchanges/spaghetti abomination thing on my way home from certain directions. I take every possible lane change and right turn for nearly 2 miles on this part of the route, so I just activate the blinker once and it stays on for a solid 3 minutes until it shuts off on its own.

• Start on 2-lane 55mph turnpike with exit coming up on the right in ~.75 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 (lol)
• 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 which I have to cross in front of
• 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 steering wheel rotation to trigger the automatic shutoff of the blinker coming out of the turn
• I grin like an idiot and cackle with glee the rest of the way home as my partner in the passenger seat quietly shakes her head. Fucking glorious
