It's possible in Sweden because these "aren't cars, they're tractors". They're required to be modified so they can't go faster than 30 km/h [~18 mph] (or is it 50 km/h [30 mph] nowadays, I can't remember).
It's a remnant of wartime legislation, when farmers had a genuine need to be able to use modified old cars for field work, because real tractors weren't available. In return for the lighter taxation on farm equipment, they were glad to accept the requirement; probably had to gear them down anyway, to be able to pull a plow etc.
So they're legally registered as tractors, not cars. The moniker "EPAtraktor" has nothing to do with the US Environmental Protection Agency; it's an originally derogatory reference to Enhets(P)ris(A)ktiebolaget, a long-defunct low-price retail chain. So, ~ "Dollar Store tractor". (Or "Alepatraktori"?)
