As Tesla gains popularity, I have noticed it is becoming more and more difficult to secure a free supercharger parking spot. Tesla needs to spend more money on getting additional slots in parking lots in order to meet demand. This can be expensive from a capital expenditure point of view. Given that labor is relatively inexpensive in Hong Kong compared to the cost of installing more supercharging real estate, hiring valets might be more cost effective option. It also takes the inequity out of it. Once a Tesla is fully charged, they move the car to a normal space. If the spots are full they will waitlist your vehicle until another car fully charges. The incremental cost would be far cheaper than trying to purchase or gain rights to additional supercharging slots. Meanwhile customers know they can get their car charged and enjoy a valet service. Its a win win for everyone involved.
