Gizmodo: Siemens VDO has developed a new system that ‘reads’ traffic signs whilst you’re driving.
A camera scans the field ahead while an onboard computer searches for patterns.
In the case that a speed limit sign is detected, a windshield display will place the new speed limit next to your current rate of travel.
The system can also be configured to automatically adjust your cruise control accordingly.
The system will be commercially available in 2008.
