The way car theft has been eradicated?
Looking at the statistics[1], I see that in my country (Australia) there is a less than 1% chance of your car being stolen in any recent year. That seems to be pretty low, a nuisance yes but not all that bad. And that's even though cars are much more valuable than bikes - and very few people use any sort of aftermarket lock with their car.
I would say the law has dealt pretty effectively with car theft and I see no reason it could not be adapted to include bikes, too.
Also, I remember seeing a 60 minutes (or some show) on south american cities where a high percentage of the cars on the road were stolen from the US.
