Low-tech driver alcohol test   (+1)  [vote for, against]
Car ignition interlock

The ignition key must be introduced without touching a small ring surrounding the lock. The ring must communicate their vibrations to a piezoelectric device to measure the strength of the key when hitting. If the driver fails introducing the key, and depending the strength of the measured force, a timer would block the iginition system for a proportional time.

Hell, it takes me a minute to find the key hole when I am sober.

Key is shaped a little complicatedly so a drunk person might insert it upside down and fail the test.
