Ok i guess i should start... Plugin is called:
Whos that slow jerk infront of me.
Machine vision utilizes digital cam on windshield or in front and uses OCR to read plate of car infront. Plug-in retrieves information related to plate number from DMV through internet. And displays all relevant data on display. That could include make and model of car (it could also display top speed, mass, and so on), name of owner, phone number of owner (just in case driver is hot chick).
Now i would reserve this idea to myself... but here in funland... although u can access all information i mentioned through net, its costy... well not much but if process would be automated... driving would cost lot more than gasoline... so this is better to be implemented in some other country where information is not only for rich and beautiful.
