Car crime is always a problem except there is a company, E2V, who have developed a system where radio signals are sent at the car to effectively shut down the engine of a car.
Now I think the owner must have been playing a little bit of NNeed for speed possibly?
But If I had a nice car which had been stolen and I knew my local force had this tech I’d sleep a little safer.
I do wonder if you start the engine back up, will it work or will it have just fried the engine ECU / electronics. I know Wiring looms are pretty impressive bits of kit themselves now.
