I also hold my dog leashes like reins, and cluck at them. My husband just rolls his eyes.
When I drive I do the “rolling slowly up to the stoplight hoping it will change so I don’t have to brake” thing, even if it’s my regular car and not my truck and trailer. My regular car is an EV, though, with one-pedal drive so that actually works pretty well, lol. One of my horses gets really angry if we are on a long trip and I have to stop a lot, so I try to minimize it to reduce the amount of pissy stomping that goes on in the back. Horse version of “are we there yet? WHY NOT???”
