We all know how modern cars without alloy wheels have those cheesy plastic hubcaps that are designed to warp and break extremely easily and fly off on a regular basis. I rarely see a car with a full set. 
Well this guy I parked next to had clearly had enough of it.

Actually rather brilliant solution I thought. 

(Sigh!  I remember a time when hubcaps were metal and it took a crowbar and a mallet and extreme force to get them on and off)
PS:  I would have passed out after discovering the Velcro on the top bracket!  Seriously, what the bloody hell were they thinking?
