........ why induction might be better than using a conventional dock, especially for an automated car.
More resistant against vandals.
A plug-in point on a post does not seem particularly vandal prone. Avoid putting them in vandal-prone areas - cars are generally more mobile than vandals.
doesn't take up real estate with a charging station
Except for the credit card reader, unless everything is going to be free in La-La Land. Anyway, people (and entrepreneurs) will still want the adjacent shop to buy their booze and fags when they top up, so a few charging pillars wont make much difference.
No need for a person to hook up the charger.
no need to play with adapters
no cables to trip over
A hard connection could be automated with a connector descending from the car to sockets on the ground. Some types of tram used to do that years ago. We are talking about self-parking cars aren't we? Even conventional cars do that now, so positioning is not a problem.
Contactless charging would be a bit more convenient than a hard connection, but seems unlikely to outweigh the penalty of energy losses in this "green" age. Seems to me that the main point is with regard to self-driving cars - that the car could be sent off empty to top up somewhere unattended, although as I said even a hard connection could be automated.
