I’ve now charged at a few upscale places in SoCal, such as Brand at Americana in Glendale and Fashion Valley in San Diego. These places all have many stalls, up to 20, but are easily full during meal time and pretty much all day on weekends. On numerous occasions, I had to wait, up to 30 minutes.
We all know Tesla isn’t cheap and Tesla owners prefer theses upscale establishments over shopping centers with Walmart or Dollar Tree. So these are essentially the watering hole of Tesla vehicles. Tesla should add more stalls at these locations. I believe even if doubling to 40 stalls, Brand and Fashion Valley will still be at full capacity regularly. Adding more stalls has to be a win/win/win proposition for the mall, Tesla and owners.
Charging price should still be fair for all but idle fee can double, triple or even quadruple at these establishments. I think too many people are willing to pay such meager penalty to finish up the meal, complete the manicure or pick the right diamond ring at Tiffany. $60 for 60 minutes may not deter them to play nice but $240 just may.
Lastly, Tesla and the mall could also offer valet Supercharging, a group of stalls separate and not available to self-park. I wouldn’t mind at all tipping $5 - $10 to have someone park for me if all stalls are occupied, do the charging when available and move my 3 to another spot upon completion, so that I can spend all day at the mall if I choose to, without constantly checking the app or disrupting my activity to move my car.
