I agree with the previous comments that the only problem mentioned is a possible obstruction of a fire truck if the passengers stop pedalling. It sounds like an interesting way for tourists to see the sights, enjoy the local brew and have a bit of excersize to add to the mix. The downside as mentioned in the article is that the vehicles are slow and the bikers are drinking. If the problem is that the beer bikes are slow and hard to steer then perhaps the design should be changed to make it lighter and easier to steer or make it so that the passengers can jump off of the bike and push the bike out of the way. If the problem is that the passengers are getting obnoxiously drunk, then it would be better to reduce the amount of beer served.
It does sound like a typical politician jumping on a soapbox for attention to a problem that is not as bad as the politician makes it to be. The police should have information about accidents or blocked emergency vehicles to back up the claims.
