Siemens reads road signs for you.

This new Siemens product is so usefull for careless people. System has a special camera to scan the field an read the signs, and warn you for speed limit. But there is a little problem for reading a signs. only known signs can readable for siemens product.

For example when a speed limit sign is detected, a windshield display will put the new limit next to your actual speed. System going to production in 2008. I think we will see it some concept work.
