When you have a broken motorbike, someone comes around with a truck and takes it away. I sort of assumed it was the same with cars.
Yesterday I explained to the garage that I can't drive the car to them because the terrifyingly loud bangs and rattles imply it's about to explode or otherwise fail catastrophically, so they have to collect it. They seemed a bit surprised that I was willing to drive it home after they repaired it, but I assured them it would be safe after they've fixed the problem and done an MOT on it.
Now I realise why they found this odd, as the man who collected the car this morning wasn't connected to the lorry parked outside. He just drove it away under its own power, complete with possibly fatal undrivableness, which I could have done if I had no sense either. Do car menders not come with lorries or brains?
