My last flat was in 1983 or 84, a rental car. Took my partner and I less than 2 minutes to put spare on. Important business meeting. Flats seem to have been much more common when I was young but just seem rare today.  More likely the car's electronics will cause a problem. If often on construction sites or off road, I can see more need.

I agree but the idea is for when you are at a place like BH parking lot. You come out and you have a flat tire. Maybe you can change the tire easy enough, maybe those lug nuts are frozen on and it's a struggle.

This allows one person to get on the road in minutes. If you have a SUV type vehicle where the spare tire is underneath, many times people find the spare is low on air because they don't check it regularly. This fixes that problem.
