What's the most petty/pointless/pedantic hill you're willing to die on?
For me, it may be that the toilet paper roll needs to have the open end away from the wall. I don't want to reach under the roll to take a piece! That's ludicrous!
That or my recent addiction to correcting people when they use "less" when they should use "fewer"
What they have started doing at intersections around me with both directions are green is that the straight lanes get a green light and the left turn lanes get a yellow flashing left arrow. It makes so much sense.
Depending on where you are, there can be veeeeery good reasons to do that. Wait until a truck pulling a horse trailer, or a tractor-trailer with a load of logs comes up the road on your right. Now it takes a left, and scrreeeeeeeeeeeee ... there went your bumper and mirror. Sure, insurance will cover it... after the long, dragged out court case, the backup at the body shop, and the newfound wonder at how much those stupid body panels cost.
It can also just be the cause of some extreme stupidity as the truck gets 'stuck' and you are now stuck at that light for minutes as it laboriously backs up and pulls forward.
Where I lived quite literally had the lines for the town's intersection painted so that it didn't happen. You could tell when people from 'elsewhere' were passing through, because they'd pull past the painted stop line in the left turn lane to be even with the people going straight.
Meth, turning wide. Space cadet texting, turning wide. Huge lift kit pick ups with duallys that need all the space because they're hauling trailers. I'll be tucked away safely away from the line.
