On principle I'm opposed to adding more irritating and potentially unreliable gadgets to cars that are already full of useless gadgets. This includes anti-booze gadgets. People who aren't drunk drivers suffer the cost and maintenance of such devices when they have not exhibited behavior that warrants them. Better to have courts require DUI convictees pay for and install the devices in their own cars.
Responsibility can be mandated. Have an accident, your blood alcohol is checked if the officer thinks you're boozing. Why not require checking cell phone records? If on a cell at the time of an accident you're At Fault - let the insurance companies work their magic. Trouble is, this all happens *after* the accident and does nothing to prevent it. We have become obsessed with Demon Rum when it is *not* the highest priority for improving highway safety.
Should people be responsible? Yes. Are they? No.
Add this to the idiocy: CA now requires the use of hands-free devices while using a cell and driving. Of course, you can still dial the damn thing (mind and eyes elsewhere) and text messaging while driving is permitted (mind and eyes completely out of the driving loop). Un ****** Believable. Only an industry lobbyist could come up with insanity like that.
