I once a had a car (Capri I think) that would select first and reverse at the same time and was a nightmare to get out of gear again, it done this on and off for about a year before it died.
I had the fuel pump die on a Ford Zodiak about fifty miles from home, I repaired it by making a new diaphram from a crisp packet, it got me home with a few more replacements.
I also had a Ford Anglia with a dead fuel pump, to get home I tied a fuel can full of petrol with a fuel line attached to the roof and gravity fed the carb all the way home, about 30 miles.
You could do this type of "get you home" repair with modern cars, far too complicated these days.
In those days motoring was about knowing how your car worked, not just putting it in a garage at every little sniffle and splutter.
I also drove a Morris Minor 70 miles with absolutely no foot brakes at all, I braked purely by handbrake and going down long hills by rolling down forwards with reverse gear selected and foot on the clutch, to slow down I just lifted the clutch a little and used reverse gear as a break, I done it that way so I didnt burn the brakes out on long down hill runs.
Stupid I know, I wouldn't dream of it now, so dangerous!! young and foolish!!
