Let&#x27;s say for instance we wanted an RFID indicator for each lane every 200 feet.<p>You&#x27;re talking about 13 million RFID chips that would need to be installed on 164,000 miles of roadway - just to get the interstate highways covered.<p>Now think about the fact that these chips are going to need to sit static and not be replaced for more than 15 years at a time.  So you have to come up with a way to house them such that they will not be affected by &gt; 150 degree heat or by &lt; -50 degree (F) cold.<p>And then think about the fact that it takes ~6 months for the government wheels to spin in the right direction for a pothole to be filled in.<p>The project to put RFID, or any new technology on the roadways in the US will have to involve federal cooperation as well as the governments of 50 states and countless local governments.  It will be 100 times more expensive than any other venture using the same technology.<p>Look at the Big Dig project in Boston.  It took 25 years, $24 billion and several acts of congress to get it to a state where they could start working out the kinks like &quot;why do the guardrails keep killing people&quot;.<p>The scale of solving this problem &quot;the right way&quot; is incredible.  I don&#x27;t disagree with you entirely.  But I think any change like that is a solid 100 years out into the future.
