No tips, but when I was a firefighter, one engine had a 1 up, 2 down "H" shifter - and the other had a 1 down 2 Up shifter. Drove me batty.

Then there were the other trucks, each with a different light package for the blinky lights....I was a driver on all but one of the 5 pieces of apparatus and it was always a concerted effort to remember where to put my hands and feet to make things go and stop and bleep and boop.
