Was sick of cans and bottles rolling around in the footwell of my car after going to the shop or drive thru and getting more than 2 drinks, as the car doesn't have more than 2 built in.
Devised this solution to hold them - I placed some hook velcro on the base of the tray and it shouldn't move around when placed on carpet.
