In Western Japantown at the river, there are two objects floating above a column. I've included screenshots and the location.

There are literally thousands of floating items everywhere.

It's the future, of course things can float.

Floating objects are probably the most common bug i saw so far:/
The second one is with getting in/out of cars where you character stands for a second and looking through the roof, it looks f^^^^in ridiculous and only shows how bad was their beta testing (if there even was one).
