I am firmly of the opinion that punishment for any type of drink driving should be severely increased. I was hit by a drunk driver who sped through a red light into my door. Luckily I was in a tank (Rover 820) and she had a Nissan Micra, but I still got pretty bad whiplash and my passenger was laid up for 12 months with injuries.
None of the Micra passengers were wearing seatbelts, so at least the driver got some payback as the girl behind her forcibly pushed her through the steering wheel, dashboard and windscreen.

Now if I see anyone who even looks drunk in charge of a car I phone my friendly local police and get them breathalysed. Caught 5 so far. Just call me El Vigilante!!!
