The video PSA is meant for New Yorkers, but applies to Chicago and to Hyde Park as well, where any number of adult douchebags do this.
Note: it's against the law. Further note: when you do this, in addition to being a blatant douchebag, you are a hazard to pedestrians -- especially small children. So your fear is not an excuse. Don't like the road? Get off and walk it.
Further note: These people need to be ticketed. In some cases, they should (and can be) arrested. The last 4th Ward Alderman agreed, but pointed out that the way to make it happen was to raise the subject at a CAPS meeting. I'll see you there.
Furthest note: got video of a douchebag like this in HP? Send it to me.
