You can only only make a staw so long. This is definitely short enough (I think the max on earth is like 9m but don't quote me on that). What will happen is that as you suck harder and harder it will start to draw a vacuum (at this point you couldn't use your own lips, you would need some sort of pump) and the liquid in the staw (assuming its water based) would start to boil.
Just wanted to share that.
Not to disappoint you @smitty but when introduced all texting and cell phone use were just a secondary offense. But the police figured out this could be a source of income. So...it's a slippery slope. But police are gonna make money, even as ad-on.

Eating and drinking is classified as a secondary offense that they can cite you for if they are already pulling you over for something else.
Frankly, I don't think it will stand up in court on the grounds of infringement of civil liberties, especially given that some forms of cellular use is still permitted.
