It struck me as odd that we used to have a "luftpumpe" attached to our bicycles at all times when we were kids. How often did we really have a flat? And when we did, then nobody seemed to have an inner tube or the tools to fix the punctured one anyway. So these Luftpumpen ended up as water cannons in the pool, being light-sabers and generally just deadweight.
Nowadays, cars oftentimes don't even carry spare wheels anymore. There is a kit that helps you inflate the tyre in case of a puncture.
My point: ditch the Luftpumpe as they are only helpful in very rare cases.
