Just to bolster your point, I rented a U-Haul trailer for all my stuff last time I moved, including an enormous 3 piece solid oak entertainment center, and pulled it with a vw Jetta wagon.
My uncle had 3-phase to his house for a heavy duty workshop, so it is possible, but I believe he had to pay a lot up front for it, significantly more than a single phase 240V hookup to a new house would have been.
That could at least be somewhat useful... It's more like grabbing some random stranger and asking what their aunt thinks might be on your mum's shopping list.
You sound like my former boss. He once told me "I hate arguing with you, because you usually win." I was too stunned to say anything in response, but of course a minute later it occurred to me I should have said "you could try not being wrong" or something like that...
I had a girlfriend who had a car with popup lights. Never had a problem with them not popping up, the problem was that over the years, the repeated flexing from opening and closing caused the wiring to fall apart. So the lights would perform their secondary function flawlessly, but fail at their primary function.
Most likely defenestrated.
