Speeding off in a stolen car.the thief thinks he has got a great catch.But he is in a nasty surprise.The car is fitted with a remote immobilizer,and a radio signal from a control center miles away will ensure that onee the thief switches the engine____,he will not be able to start it again.
For now,such devices____only available for fleets of trucks and specialist vehicles used on construction sites.But remote immobilization technology could soon start to trickle down to ordinary cars.and____be available to ordinary cars in the UK____two months.
The idea goes like this.A control box fitted to the ear incorporates____miniature cellphone,a microprocessor and.memory,and a GPS satellite positioning receiver.____the car is stolen,a coded cellphone signal
