RE:RE:RE:RE:RE:RE:RE:RE:RE:VDSSheet even my Honda Accord has the ability to read speed limit signs, read lane separation lines, sense objects in or about to enter its path. Look up your own manufacturing info if you want it. Try a google search, heard it was a pretty good technology for looking things up. Try putting in Speed detection systems. And spend a few days researching all the companies that come back in the response.
