(Dychmygol Electric cars don't have gears, it's ok! They're about 5% of the engineering complexity of a petrochemical engine, basically just a battery and a very simple sealed electric motor or four)
I set off on my usual trip to see mum, three hours away. Half an hour inn I stopped at a dodgy Spar type place in a rough area, needed something to drink for the trip and not realising how rough it was.
When I came back out of the shop and got in the car, the next door car wound its window down and a dubious looking bloke starting waving and gesticulating at me. Oh god... But I wound mine down, and he very kindly let me know my back tyre was flat. Yay.
So, I go to change the tyre, no problem. Turns out the car only has one of those shitty "50mph max" skinny spares, and it's a little bit low on pressure. But I carry an electric pump for just this sort of thing! Five minutes later I've got a nice workable tyre, ready to drive back home and swap cars with my DP and then set off again.
Except my car doesn't start. I'd not had the engine running while running the pump, and it had flattened the battery.
So call up DP, who half an hour later turns up with jumper leads and we get mine going again. At this point I really should have given up the whole thing as a bad job, but instead we switch cars, DP takes mine home (and during the week gets the tyre replaced), and I set off again. Only five hours for a three hour journey, that's fiiiine. I've had worse on that trip from diversions around roadworks...
Oh, then there's the one where my motorbike puttered to a halt and I spent four hours waiting for the AA on a dual carriageway leaving north London, surrounded by (I later learned) three major road accidents and a closed road due to flooding. When the chap finally got to me he took one sniff and told me that I had a tank full of diesel.
I'd just filled up from an unleaded pump, and had the receipt - for £6.66, numerology fans! - to prove it. Bastard bloody petrol station supplier had misfilled its tanks.
