As a person who WALKS on the sidewalks and doesn't drive, please, please park correctly. It is very upsetting to me to have to take my child into the street with moving cars so that we can continue our walk when you are parked on the sidewalk.
I'm sure you don't think you're doing anything wrong but the fact of the matter is if I or anyone else gets hit by another car while we have to wak in the street due to you blocking the sidewalk, we could easily sue you and you'd be liable. Please park correctly.
Moving off my soapbox.....
