       | There is a reason EV have shielding around the battery pack. Now
       | they want to beam it under the car? This will just add time and
       | money to road work and make maintenance harder and more
       | expensive. It's not efficient like normal charging and if we were
       | to go completely autonomous "normal" charging via plug is much
       | more economical, faster and safer.

         | Efficiency is an open question, though.

           | Changing your whole infrastructure seems very wrong to me.
           | Imagine if there was an issue with one of the substations
           | suppling power to the area or a blackout, your whole public
           | transport is going to shutdown seem like a strategic failure
           | to me.
           | 
           | At least with current EVs you'd still be able to drive or
           | power your home.
