Same in Sweden. It's not so much riding the bike though - you can actually lose it by just being drunk walking too.

Wait, how can that be true? I worked in Gothenburg for several months a few years back, and there is a strong drinking culture. My poor language skills and memory may have me wrong, but all pubs advertise 'stor stark' happy hour, which means the beers are big and strong. If drunk walking can get your license revoked, how are there so many cars on the road?

You aren't going to get your license revoked because you are drunk, even very drunk.

But if you are the kind of person the police takes care of on a bench multiple times then it's within their (or rather the relevant authority, not the police) power to consider a person "unfit" for having a drivers license. Won't happen to "normal" people, even if on a bike.

And if you don't have a driver's licence?

See, this is where the intention of the law sort of falls apart - because in that case, you are only given a fine. So the punishment is disproportional towards people who have a driving licence. People who don't have one are punished a lot less for the exact same offence.

This reminds me of the old joke about the preacher. He is giving it the full fire and brimstone treatment, shouting that in hell there will be weeping and gnashing of teeth at the eternal punishment. One cheeky young lad asks, "But what if you have no teeth?" The preacher roars back "Teeth will be PROVIDED!"

I think you already know this but: laws, like life, are unfair (well, Judicial Laws. Only the laws of nature are truly impartial).

Only if you're caught driving it on the road.
