Actually, the explanation is wrong. The primary reason why those small cars appeared in Europe all over (See Goggomobil, Ape, Reliant Regal, Fiat 50, Mini) had been plain economics. The industry was more or less in ruins, and people wanted cars.
So, the industry build what it can build and sell. The drivers license worked maybe better in the UK than in Germany.
Same why scooters became so popular in Europe during that time.
But its really funny to see a car that is even small for German standards (even at that time!) on a US road. :rofl:
