What do we do with boy racers?

Boy racers are in the news again after the death of a 20 year old in an illegal street race in Tauranga on the weekend:

So what are we to do to stop these boy racers drinking then going and racing their cars all over the show on public roads? Some suggestions are 24-hour liquor bans in public areas, reviewing all liquor laws and reviewing the licensing, sale and financing of high-performance cars for drivers under 20-years-old. Well, guess what, those suggestions are not going to work. The boy racers are just going to continue with what they do anyway. What they do now is illegal, so these proposed laws are not going to make any difference!

This is what I think should happen. On their first offence the Police should confiscate their car, either for a period of time or permanently. Cars mean everything to these boy racers, so confiscating their cars will make a huge impact on them. But, as with the wonderful legal system in this country, this won't happen. We have to be "nice"...
