Good roads and good cars, its always man vs machine, its very tempting to put your foot down when you see a straight clear road ahead giving a chance to test your beloved cars capabilities. Especially when you have spent quite a bit in buying your toy.
It also is a way to put to use all the horses that have been built into your cars muscles. Law enforcement is the other side of it, in an attempt to safeguard the interests of other public users of the road and pavements, officials usually stand their stance in ensuring that safety is not compromised.
Thus arriving at a conclusion to introduce Lamborghinis to cops who can now chase getaway speed violators and make sure that they face the law of the land.
Another way to look at it is, its cool to see an Lambo in every corner of a street!
