Earlier quoted context omitted.
In Texas, you receive a mandatory suspension for refusing just a breathalyzer, even if you are found to not be over the legal limit, or are never convicted of a DWI. Blood tests are then often obtained via warrant (and it's typical to have a judge "on call" to sign and fax those orders on demand)
That's utterly disgusting that the state can invade your body and take blood out with a warrant.
My understanding is that GA pilots are not allowed to fly within 8 hours of consuming any alcohol (my understanding is that most commercial outfits have more stringent limits) - I personally think this makes a lot of sense for operating a motor vehicle, too.
