As far as I know it is only used for electric buses at moment, and 
doesn't seem to big or heavy enough to attract attention.

Magnalev trains need to shift a lot more power through the inductive 
link, and it doesn't seem to make them impractical

Since a car typically spends spends 95% of its time parked, charging 
doesn't necessarily have to be all that fast.

Aluminium coils do tend to be bulkier than copper coils, but they are 
quite a bit lighter and cheaper.

If you had any grasp of engineering design I wouldn't have needed to 
spell this out for you.
