As I sit hear reading through some threads, it occurred to me that we could have tiny signs which would work very nicely. Problem is, we need to get our autos up to speed with onboard computers. So here is the idea, you have a sensor in your car which is able to receive information from a microchip when you go past a "sign." The sign might even be underground, so as not to interfere with view or other things. Depending on the sign, the State, County, or even TDC might program the info on the sign. People could even install their own signs on their rental houses, at the mailbox, listing the address, website, and other public info they wanted people passing buy to know. Restaurants and businesses could also buy in to the system. From your car, you would have a computer screen, maybe with split screens, so that you could see the signs most recently passed. For example, one could choose to see the speed limit, name of road currently on, or cross street most recently passed, street addresses of properties which you are passing, businesses names, town/city/state/zip. Each screen would have at minimum, the road hazard signs, stop/yeild etc, and speed limits. On top of that, the user could block everything, or pull up all of the info to show simultaneously. Maybe a voice announcement would be good too. Even invisible billboards could work, notifying people of upcoming restaurants, gas stations with current prices, or restaurants with lunch specials and prices, etc. One could go as deep in their search for info as they wanted to, going straight to each business's website. blah, blah, blah. I'll take ten percent of the profits if anyone wants to bring the invisible signs to fruition.
