Just as many as there are parking in handicapped stalls or too close to corners or taking 2 spots. I hav no problem with making the fine quite hefty, say $500-1000, because it is a matter of preserving public and private property and sometimes lives. That doesn't mean I condone doing $5000 worth of damage to somebody else's private property to prove a point when there is another viable option for routing the hose. If there is absolutely no way to go over, under or around it then sure, smash the glass, but that should really be the last resort, not the first option.
