I've been very happy with my folding bike ever since I purchased it 20 years ago. It has enabled me to take my bike with me on many trips where a regular bike would have been too much trouble or expense - or banned by regulations of many public transportation systems that I utilized.

But I was struck that someone would cite as the only reason for getting a folding bike that he couldn't transport his regular bike using his private car. Since I daily see numerous people carrying their non-folding bikes in or on their private cars this seemed like an unusual rationale. From my personal observations I'd conclude that there are at least an order of magnitude more non-folding bikes than folders being transported by private car.
