Not a new idea. I saw that on that technology programme that comes on Saturday or Sunday mornings a couple of years ago. Inductive charging via the road surface.
 
I wonder what would happen to a car with a low ground clearance steel body pan that went through an active charging zone.

Ooh, you've given me an idea!
Hack the system; turn it into a railgun! :D

This might also create some interesting effects!:

yea, i saw the idea to have house driveways and garage floors enabled for car charging - i suspect that will happen in time
 
Apple already do it with their phones, perhaps they'll get involved and who knows they may even spy on our cars too.

We did - I remember them well (particularly, as a kid, watching them 'turn around' at the end of their run!). However, one doesn't have to think of the past given how many trains now use overhead electricity.

Kind Regards, John
 
there are so many variables to worry about

a magnetic feild will have a sweet spot i would think with a greater or smaller distance less efficient at transfer
you will get magnetic forces that will to some extent affect the vehicle handling and may upset the balance and change stability
there will also be drag on the vehicle that may or may not be significant on the mileage range
there are also perhaps around 40% losses so 40% more energy need to be used for the same distance increasing costs per mile
