yes, or poor engineering. In the case of my VW, the oversize rear tires
acted as an overdrive. Had it been left per Dr. Porshe's design, it would
have run out to a better top speed. However, being broke and cheap, I left
on the oversize tires and imagined i was saving money by lowering engine
RPM/road speed.

You can't beat my BMW Isetta though for proving there is always an
exception. It overrevs if you try to exceed 38-40 MPH in 3rd gear. 4th
(top gear) will take you to 54 mph. It matches your criteria, low power,
298 cc, 13 hp. If you've seen a rolling egg you know about wind resistance.
I think the majority of the time you see the phenomena beign talked about
is when overdrive is involved. The drive train is geared to run up to to
1:1 ratio and then when you engage OD it is for economy not speed.

Not at all uncommon at all. In a relatively low-powered engine, a
higher gear can put you too far off the power peak to overcome wind
resistance and other running friction at higher speeds, so you can
achieve a higher speed in a lower gear. Downhill or in a stiff
tailwind, you may be able to exceed the lower gear's top speed, but
not on the level.
