Toyota announced that it’s testing a mouthpiece-free breathalyzer to keep those with high alcohol levels off the road. Similar to Volvo's drunk driving tool, drivers blow into the handheld device, which analyzes their breath without them having to put the product in their mouths.
A mounted digital camera records which face goes with which reading so an inebriated driver can’t try to push a false reading from a volunteer’s less-boozy breath.
If the alcohol level is too high (no word yet on what “too high” means), the ignition is disabled and won't start until a lower reading is achieved. This will make sure that the roads will be safer for all going driving. There is no word about when these will start to be available on existing Toyota Parts and vehicles.
