Glaubst du, irgendjemand wagt es, diesen tollen Parkjob zu bestrafen?

I’ve been fined for similar situations, but somehow think that they’ll get away with it.

No. Because it seems to be on a private property therefore nobody can legally fine you. As the driver of the vehicle, you likely know this (or ask a member of the band which can explain it to you).

Now, as it is on private property, you can get in trouble with the owner of the property. But that’s another story.

Also another story is how some of the fans of the band sometimes park on the public road during a concert. Hardly seen some many blatant parking violations.

No siren on it, not there cause of an emergency, not in the parking field.
Hell with that picture, i would demand the police to fine them. xD
