And ingo, if you are driving hard enough to cause the drink to splash out on to things, than you are a very bad driver and shouldn't be driving in the first place
Besides, with fast food cups (which is 90% of what I drink in the car), that isn't a problem at all, becuase it has a nifty little plastic cap to hold the drink in 
@Max: you must think about, that European roads have more curves (and traffic either) than the long straight US-highways.
And the European way of driving is a bit more dynamic than the sleepy US-people are doing.
I remember, how I've shocked half-a-dozen of people at my US-autodriveaway-trip in 1993 - I was so crazy (in US opinion) to pass three cars and one truck in one way!
Reason: the very slow truck was driving with 3/4 of it's wide on the emergency-lane, left of it everything was free. There was now traffic from the other direction, passing was not forbidden - but these stupid idiots in front of me, weren't able to pass this truck!!
This has sucked me, so I made a pull-down (it was a 3.0 litre-6-cyl-Buick, smaller than a Park Avenue) accelerated (very lame car for a 3.0-litre-car, but anyways) and have overtaken all in one time.
By passing I saw panic in the other driver's faces, all of them have used their horns and flash-lamps behind me.
It happened on a dual highway somewhere in the Midwest.
