I think they usually are people that never had a problem. I bet 90% (if they plan on riding more) pick up
all the essentials after a flat or 2.
If I remember back to when I started biking regularly, I don't think I took any tools. I think I rode for a couple of summers
flat free before a few flats made me pick up a patching kit. I rode for many years with just a patching kit
until someone said they carry an extra tube and just replace the punctured one and fix it when they
got home. Then I started carrying an extra tube.
