Decent performance but unengaging drive from Audi A6

As we all know, back in the day when you got a flat tyre, you simply stopped the car, opened the boot, took out the spare and the jack and the wheel brace, took off the errant rubber and replaced it. All very simple and uncomplicated.
These days, however, all is very different. Very few cars now actually come with a full-sized spare, largely thanks to car manufacturers’ efforts to reduce CO2 emissions as extra weight means you emit more nasty gasses. Consequently most cars these days come with either a ‘bicycle tyre’ space-saver or one of those completely useless kits which are supposed to seal the hole in your tyre with some sort of gunk or other.
