Sure...having an electric car would be sweet.  But every time I pull into the garage I'd have to get out, grab the charger, make sure it's plugged into the wall then plug it into my Tesla.

What a pain!  I'd rather pay for gas!

Wait a minute!

What's this you say?

A contraption that automatically finds the outlet and plugs in all by itself?  All while looking like something from Terminator 2?

NOW I'm sold!!
