You are joking! I've seen on many occasions how much effort goes into
removing/replacing a tyre from/on the rim using the specialised tyre
fitting equipment. There is also the 15/30 minutes for blowing up a
completely flat tyre with one of those little 12V compressors that fit
into the cigarette lighter socket.

I can just see all those inexperienced people breaking/chipping their
alloy rims using breaker bars.

For the money I pay to get a puncture repaired (and dynamically
balanced) by a tyre shop it's not worth the effort to even consider
Do-it-Yourself.* Without researching prices, I'll bet here in the UK the
cost of obtaining one or two proper tyre repair patches would actually
be close to the cost of using someone who does it for a living.

I'm with you. Repairing punctures was something I had to do as part of
my trade. Even with the gear, it was a pain to do, especially truck and
tractor tyres. At 65, I'm quite happy to pay someone much younger to do
the job for me.
Likewise - and my Hakepelita snow tires come with lifetime free
repair. Not sure about my Michelin summer tires - but tire repair by
an expert is a BARGAIN.

One of these days Mr Screwup is going to screw up something serious
and get someone killed.
