Unless you are currently looking at a scooter laying on the sidewalk in front of your house/apt/tent, then this is a hypothetical question. We don't answer hypothetical questions.
Yes, I trip over scooters on the sidewalk in front of my building all the time. They are literally left in the middle on the sidewalk flat or sideways on the ground. You want the GPS locations and a print satellite map from google?
I live in one of the test cities for this thing and the city console has no backbone to stop it. They are considered a annoyance for pedestrians.
You can't walk down the sidewalk without getting almost run over by one of them or tripping on them. They are all over the sidewalk, the grass, sometimes even in the street.
This is real not hypothetical. I do encounter these annoying things all the time and would like to know if they are situation that you could remove them as abandoned , salvage or adverse possession.
Houses can be worth Millions, bank account can be worth million, ships can be worth hundreds of millions or even billions. These all have situations that allow one party to take something that does not belong to them legally.
Do these annoying scooters laying in the middle of the sidewalk/street have the same legal ownership transferring situations as land, houses, bank accounts, and ships?
P.S. I did not even include assert forfeiture in which a cop can just take your stuff without even being arrested or convicted of a crime.
We are still in America right?
