The concept isn't all that new, really. When motorways were first built in Britain, they had no speed limit (as indeed was the case with many other rural roads). In 1959 when the first section of the M1 was completed, the average car in the UK was probably good for about 90 mph tops. The police pretty quickly figured out that their usual fleet of cars was useless to catch a reckless driver in something more exotic on the motorway, so they started using Jaguars (in those days an expensive luxury car). But I suspect they had to buy them. I doubt they were donated by Jaguar Motors!
The problem with reckless motorcyclists had to be met like-with-like, I guess. Do the police in Britain still use powerful motorcycles, I wonder?
Having been to Italy, a Vespa could easily elude this given some of the ancient roads and alley ways they have. Looks more for show than anything else. Where are they going to stick the crims they catch ? In the glove box or under the bonnet ? Strap them to the roof ?
Gee, you guys! It is a car for TRAFFIC cops on high-speed roads! Leaving aside the drunks (for whom they would presumably summon backup) traffic cops don't <u>arrest</u> crims - they just write them tickets and everyone goes on their merry way.
