Sadly, I read in a local paper, about this incident:
Someone illegally parked in a disabled spot at a doctors office. A disabled person arrived for his doctor's appointment, and saw that the only disabled parking spot was taken. The disabled person was using crutches, so it was difficult for him to walk. The disabled spot was right in front of the building.
He had to park further away. As he walked from his parking spot to the building, he fell in the garage and broke his leg.
Chances are that had he parked in the disabled spot, he would not have fallen. I.e., the accident occurred because he had to make that extra walk. Is the person who illegally parked liable for the damage and / or medical costs?
