I bring to the panel the following example of muppetry;
In Guildford, outside the uni/cathedral entrances is a very large RAB, perfect for the local population of chavs to practice their drifting round.
The Police may or may not be aware of this, however thanks to the fortunate geography of the A3's north and south on-ramps, the Cathedral access road is a perfect place for a traffic car to sit and await despatch. The road is hidden by the RAB if one approaches it from the direction of the chav estate.
Now, of course, most of the population of Guildford know that from about 8pm onwards, a traf plod will be sat on that ramp, and many chavs do a precautionary lap of the RAB before getting into high jinx.
Walking to the pub on campus I see a white Nissan Skyline, in full street race kit take such a lap, but entirely fail to spot the police car. Next thing is the Skyline comes round the RAb sideways, is a proper tyre-smoking drift.
Queue instant blue lights and siren.
Matey boy, has a go at running (not sure how he thought that would work, seeing how Surrey has one of the highest Police:population ratios in the country, and deploys its helicopter even for foot pursuits) anyway, his mad skillz run a little short and instead of escaping onto the A3 he drives slap bang into the crash barrier marking the edge of the sliproad.
