The reason is probably that electric cars are heavily subsidized in Denmark (via much lower vehicle registration tax) and those subsidies are lower for businesses.

Subsidies for electric cars were removed in Sweden a few years ago, so I would say 43% electric sales (and rising) is very impressive.

Prussian Kingdom was technically one state in the German Empire. But since the Prussian king was the emperor, distinction between them was somewhat artificial.

Pre-Balkan wars even.
