Motorized Menace.

Our aged condo neighbor across the hall is a wonderful guy, with a interesting character. He's a great neighbor with only one problem, he is now a motorized menace. We forgave him when he left the tap running all night into the kitchen sink, which resulted in our condo, and all the storage lockers below him, being flooded with water. We even forgave him, the second time he did it. He left a candle burning down all night, in a plastic candle holder. The black acrid smoke filling his apartment, and the hallways. After much banging on the door he finally woke up enough to open the door, stark naked. I am still traumatized. And I don't which one of us gave the highest pitched girlie scream at the sight of him standing there naked, black smoke swirling around his skinny legs, his hands belatedly hiding the embarrassing parts. He laughed that one off, saying I did not need to call the fire department, but he so easily could have died of smoke inhalation. Now he has a motorized scooter, the kind that the sidewalks, streets, and malls are teeming with. Those dangerous whirling tornadoes that whiz by pedestrians on the sidewalks. He only knows one speed, MAXIMUM. We were surprised to hear a loud repeated banging on our adjoining hallway wall the other day, it was him. He was stuck in the hallway and revving back and forth hitting alternatively the wall, and his doorway. Leaving large holes in the wall, and black marks on the doors, the scooter speed was a high as it could go. Unfortunately this was not the end of the motorized menace. A few days ago, there was a large crash, and the sound of glass breaking. He rammed the glass front doors, and broke one. He approached the front doors with the scooter set on it's highest speed. We spent the night with only a flimsy plywood door for protection. We love him, but it is really obvious that he is no longer capable of driving any motorized vehicle, and he does not understand how this scooter works. We are very concerned that he will topple the scooter over a sidewalk, or dart in front of a car. It comes with lots of safety features, but none of those replace capability. While we don't wish to limit his transportation, this cannot continue. I am curious as to how you would deal with someone that you respect, who no longer is the same person they were years ago. His family is aware of what is going on, but we have not yet spoken to them. It is a difficult subject to broach. Meanwhile, we are reinforcing all the doorways.
