And how big and heavy does the coil on the car have to be for fast
charging?

 

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.

 Yes, but when my EV is away from home. I'm probably on a long journey and
require fast charging then.

Being able to charge an electric car by parking it over an inductive charger doesn't stop you fast charging it through a plug-in cable.
Equipping the car for both may cost more money, but a socket for a plug-in cable won't be expensive, and enough customers are going to want to have the option available that there's always going to be an easily (and cheaply) fitted option.

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.
