So I have noticed this about(and ex) NBA players. When they get pulled over for drunk driving, they submit to Blood Test but not breathalyzer. Then I thought about it, and here is why they do it: If you don't submit to the test, you are automatically found guilty in most states. But, if you submit to a blood test, they can't. Here is the thing though. Officers don't carry the stuff for blood test with them. That means they have to take you to a hospital and get the test done, which may take, say an hour plus to get there and get it set up. During that time your body processes liquor and reduces your blood alchohol level. Very smart move.
