Is there a way for a car pc to tell me what the speed limit is? I have seen this feature on some newer GPS Systems, and even a few head units.
From what I have read it seems like it can be done two ways. The speed limit information can be pulled from a database stored on the device, however this requires a map with that all that data included in it. The other option is something I haven't been able to find any solid info on, but apparently Vauxhall is developing technology that uses a camera on the front of the car that recognizes speed limit signs and displays an image of the last seen speed limit sign on the dash.
Yep, here is a program that is supposed to recognize road signs (haven't had time to play around with it).
