ARE YOU KIDDING.????
If you tried any of that here in WA the cops would go all American on your arse, throw you to the ground with the knee in the back, hand cuff you and have you charged for reckless driving, especially with all that lane crossing.
I would also loved to have seen the speedo cos when they were overtaking the cars either they were speeding or everyone in the UK goes slow.
One of the reps here was pinged for speeding when he overtook on a country road, exceeding 110kph.
When he explained that the car he overtook was doing just under 100 and it would be impossible to overtake without slightly exceeding 110 to make the move safely.
Too bad apparently, still got done.
