From Peter Smith
DaimlerChrysler’s car-security system is explained thus: “To set up personal unlocking, you choose a position to send the signal from, say, three paces sideways, halfway up one side of the car…From then on, the key will only work at that point” (15 January, p 25).
If you do this, you had better hope that no one parks next to your car while you are gone.
