described was two "finish nails" through the tire. Punctured the first
time, pulled the nail out changed the tube and almost exactly 1
kilometer down the road punctured again, the same kind of nail. I had
used up the only spare tube I was carrying, the patches won't stick,
it is raining.


I was riding with a couple of mates on a wet day and one of them had
three punctures. After emptying his two CO2 canisters on the first two
punctures, he begged for my pump. The patch worked too.


I had some of those glue less, or whatever you call 'em, patches they
didn't stick well in the rain, or at least mine didn't :-(

In WW2 pilots were given a patch kit for the inflatable life raft they
carried, in case they had to ditch in the sea. These patches stuck even
when applied in/under the water.

I'm pretty sure I have patched tyres in the rain successfully. The
problem I remember is my cold fingers having trouble getting the tyre off.

While the electronics itself can get cheap, it won't. But the expensive part is the electo-magnetic actuators and since that is mechanical it won't get cheap.


Electric motors can be very cheap when mass produced.
