TBH I think not supplying a full size spare is as much about cost as anything - full size tyre plus full size alloy is a fair chunk to add on.
But also, when you have 18 inch alloys with fat tyres that's a lot space to find and additional weight to carry.
I've gone through a fair few cars over the years, and I haven't had a full-size spare for I would guess 15 years.
I'm quite happy with a space-saver. It's not ideal but at least you have a get-out-of-jail that you can sort you out until you can resolve the problem properly.
My last car, a BMW, had run-flats and that was ok too. At least you can continue your journey and get the car to the tyre dealer.
As I said in the other thread, repair kits are a disaster where the damage is too severe for them to work as happened to me. I don't mind that risk in an Elise, but not in a car like the XC60 when I am likely taking my family somewhere.
