This isn’t all that new - in fact London’s tram system was using it c100 years ago: http://1.bp.blogspot.com/-UIyXE_Fv3vA/TkLYU8vbHRI/AAAAAAAALb...
Try taking that off the rails and go shopping and see how it works. No comparable at all.

#62What is the voltage of the track?
If filled with salt water, 1 volt at the surface, but beneath?

Yes, I did read the article, otherwise I would not have been able to write what I did, note that the title says nothing about how the electrodes from the car connect to the road. So you could have known that I had read the article. Yes, the article addresses it, no, the article does not address it in a way that gives me a good feeling about the safety of this system in the presence of moisture. It really doesn't take…

It clearly states that salt water in the rail only gives off 1 volt at road level and that you can walk on it barefoot.

Although if you had this everywhere , you could probably do away with most of the batteries on electric cars, making them a lot cheaper and lighter.
It would never be everywhere at not in somewhere as vast as Europe or US. To jump on OPs bandwagon. It would make sense to have this on highways as opposed to surface streets. Distance is one of the limiting factors for a lot of people buying electric. In the US interstates are at least maintained by the Feds and are pretty standard in look and feel. It would probably be easier to implement nationwide.

No, they aren't. States are encouraged to focus federal funds given to them for road maintenance on the National Highway System, which includes the Interstates, but the maintenance is done by the states.
EDIT: missed responding to this bit—
> and are pretty standard in look and feel.
The look and feel is due to the AASHTO [0], on which the federal government (via DOT) has only non-voting membership, the same as a number of foreign transportation authorities.

You’re right. What I meant was funded by a federal program.
Re: World's first electrified road for charging vehicles opens in Sweden
#66I hope Sweden and Germany can make a common DIN Deutche industri normen standard for charging electric vehicles on roads. There would be an added benefit if we could build rail tracks among the electric guidance line. Rail tracks to lower the rolling resistance, metal on metal vs rubber on asphalt. We would then have a hybrid car rail track which should make it easy for autonomous driving. The aim would to bring down…
At high velocities (> 40 km/h?) the main drag comes from aerodynamics (turbulence, air viscosity…), not rolling resistance.
perhaps with autonomous cars and rails the cars can follow each other very closely so improves aerodynamics too.

>In the US interstates are at least maintained by the Feds and are pretty standard in look and feel. I don't believe that's true. At least in California, CalTrans does all of the maintenance on state and federal highways alike. AFAIK CalTrans does get paid by the Federal government for interstate maintenance, but that's the extent of the USDOT's involvement in interstate maintenance.
Yes as it turns out they oversee the projects and standards but the actual work is done by state contractors.

Electrified rails on trains have been around much longer than parking stations. Plus batteries are the biggest problem (and most expensive) part of ecars, so this is a good idea to try out.
But those rails are on otherwise off-limit tracks and 'third rail' solutions are notoriously dangerous. This system has the two rails closely spaced side-by-side so it may be a bit safer but in the presence of moisture it could be dangerous too. It's basically a scaled up version of a slot car track.
Highways are already off-limit and notoriously dangerous.

Not going to work in the snow belt. Maintenance on this will be crazy.
