Driving Barefoot

In the United States, widespread belief in the existence of laws against driving barefoot has been debunked as an urban legend (http://web.archive.org/web/20030618105020/http://www.urbanlegends.com/legal/driving.barefoot/driving_barefoot.html).

In Germany, a law from 1988 forbids driving barefoot, with sabots or with any "inadequate footwear".

In Belgium, the driving code does not explicitely ban barefoot driving, but article 8.3 requires drivers to be "constantly able to perform any maneuver". According to the federal police, this implicitely bans barefoot driving.

in Hong Kong, laws require drivers to be driving with appropriate footwear. Driving barefoot, or with sandals, are not allowed.

Diesen Abschnitt habe ich aus der englischen Ausgabe der Wikipedia.
Auf welches Gesetzt von 1988 spielen die denn an? Interpretiert man bei dem Autor die rechtslage als "Verbot" ?
Wir hier sind doch bisher zu anderen Schlüssen gekommen, oder?
