Inductive charging - top or flop?

Just spent some time thinking over inductive charging for electric cars and came across this video.
At first it seems to be great. No cables, more range. What about the costs? Isn't putting that technology into the road expensive? And what about the communication system connected to it. I am sure driving on such a road won't be free...and it needs service and maintenance which will make driving as expensive as it was with the good old oil
What do you think? Top or flop?

Built into roads... complete flop... for many reasons... we have too many problems keeping roads repaired now... much less with adding MWs of electrical power to them... all the bad efficiency losses ... installation costs ... etc.
For the home consumer , maybe as an eventual type of universal power plug... or a convenience charging pad built into garages and such... but only for the high end luxury EVs in the next 20 years or so.

Interesting, but old idea.
Think of the Transrapid, similar system, but very close distant betwenn sender an reciever.
In 2001 it was my job, to programm a data-carrier (and corespondig Data-drive), which was without any pin connection. Energy and Data transfer by inductivity.
Practicaly Working since years. But even at this small scale very expensive and with bad efficiency.
I also believe, that this will not come to to its cost of installation and maintainance.
But i may be wrong, because this system is very attractive.
If we find a quite cheap way to include such a system into the roads (when rebuilding a road...) and into the electric cars and achiving an acceptable efficinecy, then this system will come.
Off course only for major roads, because this system is only needed for long range travel.
And parking lots in the cities with automatic recharging of your car...
Very, very attractive, considering the long range problems of electric cars and the mechanical problems of high power plugs.
But to power or charge a "full-size" E-Car you need several kiloWatts of Power.
Transfering so much Power through the air is quit a task. I don't think there will be a way to make this real in the next few years.
Of Course this may come as a luxury option (Tesla additional recharging option ), and from there it may find its way to the affortable electric cars.
But i rather thing we will get a hand in hand working of electric cars and electric railroads. Proboably it is cheaper and more efficient to transport e-cars for long distances in small trains or building a solution close to the concept of the cable cars.
