In practice what that sounds like is well to do jerks in their nice suburbs and gated communities will be free to drunkenly rearrange their driveway (for whatever benign reason, to get the lawnmower out of the garage or something) and that people in "bad" areas where there is little political power and the .gov is more or less free to abuse them at will will found guilty and be given an option to not be found guilty if they pay into the system some other way (fine and/or driving school is the usual mechanism). Basically it will just become a side channel for revenue just like everything else about drunk driving already is.
