The very obvious answer would be “on your face,” or more vaguely “anywhere except where it’s supposed to go.”
This Celebrities in Cars Getting Coffee spoof follows George Seinfeld’s recipe up to the point where, after coffee has been acquired (to go), the protagonists stay in the vehicle and the driver hoons it like a mad man.
And, if like here the car you’re getting coffee in is a 300 hp Ariel Atom, then those lateral and longitudinal g forces will show very quickly. Aside from showing how quickly you can drench yourself in latte, this video also shows why fire truck tankers full of water can’t take corners quickly – it’s liquid physics…
In the case of the Atom, it’s not the kind of car you`d expect to find a cupholder in. But what would you need it for – what it would need for liquid dispensing is something akin a NASCAR’s in-car drink system.
