I've been on the Fisher Island ferry, the only way to get your car on that thing is to be a multi-millionare resident of the island, or a guest, and guests have to be screened. I almost got bumped because my last name was misspelled on the intake form.
The only way on or off the island is by that ferry, any any resident would know what to do. Hell, they WASH the cars as they get off so there's no sea spray stuck on their Bentleys. The cars are essentially loaded by hand with attendants.

What I'm saying is, they probably don't care about things like chocks and nets because everyone involved is kinda an expert at it. Either her car broke, or she pulled it out of park while grabbing her purse, or she had an "incident" and didn't get it properly loaded.
