I agree entirely ----for most people, of most sizes, in most cities. Manhattan is one exception, and there may be others. In spite of being very bike friendly, my groceries, hardware stories, and other everyday places tend to have squeezed aisles and even the Brompton pushes the limits of space and patience. Thinking of the last several restaurants I've been to, none would accommodate a Brompton under the table. However, there are still other benefits to the Brompton's folded size.

I hope this doesn't distract from the direction of this thread, but IMO when thinking about a folder, don't assume that you always have to keep it at your side. Evidently, many people turn to folders because of security concerns, but appropriate locks and chains still have their use. Locking up a folder does not wipe out the other benefits (for me, the chief benefit is getting on any bus or train with the folded bike,) so assess your security needs when figuring budget and overall use---much the same way that you'd consider a helmet, and accessories such as lights etc.
