BMW unveiled a "significant advance in anti-theft technology" — Driver's Weight Sensors:
"DWS stands for Driver's Weight Sensor. A unique system that compares the driver's weight with a pre-programmed value stored in the sensor's computer memory...
The sensor weight reading is then compared to the programmed weight in the memory, and provided this falls to within ±5%, the car will start normally.
If, however, the figure exceeds these tolerances, then a discreet gong sounds, and the entire ignition system is shut down."
Interested readers were urged to contact Hugh Phelfrett at BMW.
