Can anyone honestly say that they haven't broken the law when behind the wheel ?
Speeding
Undertaking
Leaving the engine running whilst away from the vehicle
Using your horn to attract a shopkeeper
Tailgating
etc etc
We may see them as minor or even a nuisance, but they are all illegal.
Is someone doing 140kph in a 100kph more dangerous than someone driving up a one way street the wrong way to avoid a roundabout, or double parking and blocking a road to pick up his dry cleaning ?

Lets face it, we have a choice. Obey the law or face the consequences.
But we all know that no one is innocent.
