Well not quite and it's not racing but I just heard of yet another cunning theft trick in the UK.
Apparently if you have keyless car entry fob then the car sends out a continuous low energy radio signal looking to " handshake" the key fob and so open the car and let you start it up and drive.
Normally with the keyfob inside your house all is safe but crooks have developed a booster gadget which re-transmits the handshake signals. So they get near your front door and relay the radio signals back forth to the car allowing them to start it with your keys safely ( you thought) in your home.
The suggested fix is to use a metal or metal screened key box in the house to block the relay signals from the theft gadget.
So not quite a Faraday Cage but nearly!
