Driving...again

Today I witnessed the following:

• Tailgating at 120KPH
• Exiting from the left hand lane across 5 lanes at the last second at high speed
• Lane weaving on the freeway 
• Overtaking on the inside lane
• Using the emergency lane to overtake
• Speaking on the phone with one hand, holding a cigarette with the other and steering with the knees
• Reading a document while driving at speed
• Jumping a red light - by coming from behind the second car that had already stopped
• Weaving round pedestrians already 1/2 way across the carriageway

Now this is all pretty routine stuff; I doubt a journey goes by anywhere in the country where you would not see all these behaviours and more.

But these were all POLICE cars.  What chance of change do we have if the police don't even try?
