I love it when artist question definitions.
Artist Michel de Broin guts out a 4 person car and adds pedals to it rendering it a 4 person bike to some extent with a skin like a car. Is it a bike or a car? Car’s need a license plate, bikes do not.
The trekkers ride it onto the streets and get stopped by cops eventually. The best part is that during their stop a fleet of police bikes pass by.
Rules and definitions are meant to be broken, questioned, redefined. I love it when these instances are documented!
