RFID tags are becoming ubiquitous. Even KMart has a love affair with the things.
If local municipalities want to start saving money then they could do away with a whole lot of road signs, replacing them with RFID devices attached to posts, fences, embedded in the road surface, wherever they can
be stuck.
A simple receiver/advice unit in the dash instrument binnacle keeps you informed of traffic advisory warnings, speed limits, obstacles and many other things. Being inside the car, it would be simple enough to customise with voice messages and cues.
Welcome to the 21st century.
Mad cow RFIDs

It seems to be accelerating.

What's an RFID tag? link please... |
|

Finally we can get rid of all those road
signs in the public space. Good. |
|
| |
But how do you prevent spam? You
would need a whole new kind of law
enforcement unit on the roads trying to
find the illegal broadcasters RFID
spammers hide. They will dig tunnels
under the road to place their
broadcaster there. |

It's a Radio Frequency ID tag. A low power device that transmits a small suite of information to any enabled receiver in the area. Department stores have begun using them, to store security and product data, for checkout scanning equipment to disable security, inventory control to "count out" sold stock, etc. |
|
| |
[rrr], prosecute the companies doing the spamming. Restrict usage of the bandwidth to official use only. Whatever. |
|
| |
I also figure that any technology that goes to reduction of roadside furniture is a good thing. |
|
| |
I am stunned at the number and proximity of utility poles and "hard" objects implanted in road verges. |

RFIDs don't transmit very far. Passive RFIDs, the common, cheap kind, can be detected to a distance of about 6 inches at the most. Active RFIDs require a power source, are much more expensive for both the tag and the reader and still only make a few feet. They are, in practice, a replacement for a bar code but have the advantages of being able to be read simultaneously in groups of up to 50 at a time and require no special orientation or lighting to be read. |

The Use of the word 'ubiquitous' is also becoming ubiquitous. Is it just a zeitgeist thing?. Linky.
+ for the idea. |

It's simple, it's a good idea, it should
have been here already. ++ |

[gnome], 71 instances is hardly an overwhelming representation, even for a truly obscure word, let alone one in moderately common usage. |
|
| |
I just seemed to notice it more recently. Maybe so. |

This idea is popular. This is one of at least three nearly identical ideas already on Halfbakery. |
