I've never been recovered a long distance home, but I was warned by one of the RAC guys that it would take at least 24 hours to get to Nottingham from Edinburgh. I was able to get a local recovery guy on standby to take me for £200 in one go, but he wasn't needed. The car was repaired in his mate's garage instead.
They work a relay system. We did the same "duwing the waaaar". Each recovery wagon was responsible for keeping its own area clear of breakdowns. You can't do that if you leave your area, so you recovery to the next area. It works for the recovery company, but the casualty takes longer to get home.
A warning tale of how the simplest fault could halt you in your tracks...
A tale from last month. The driver's wiper blade flew off in Egremont, Cumbria. It was 1730 on a dark, windswept Friday night and everywhere was shut. I swapped the passenger blade over. Luckily, the failure had left the stump of the blade on the arm, so the windscreen wasn't getting scratched. We made it to the hotel a few miles away, and called the RAC. After about four hours, RAC phoned to say they had no wiper blades for a Range Rover. It turns out that this was quite fortunate, as it could have been embarassing.
The rear wipers and the front wipers are different fitments.
Next day, we started to drive home via every motor factors in Cumbria. Nobody had wipers with the correct fitments, not even the Range Rover dealership in Carlisle, but one of the motor factors did have Rain-ex. I usually get two bottles for £8.50 in Costco. This bottle cost me £15!
It would seem that one of the previous owners had fitted new arms and blades, but the blades have a very uncommon (B9) fitment
One of the motor factors found some blades on Amazon and I got my son to buy them and have them delivered to Nottingham. They were in the house before we got home later that night.
In hindsight, we could have sourced them, and had them delivered to the hotel, but you would expect wiper blades to be commonly available, wouldn't you?
We made it home thanks to Rain-ex

I now carry a spare wiper blade.
