2 or 3 parking spots. It's a token gesture, not meaningful infrastructure. Electrifying an entire parking lot is a lot more expensive than 2 or 3 spots.
You don't need to electrify the entire parking lot.
Even if you do, not every parking spot needs to have a 350kW HPC charger. 11-22kW is more than enough. Add load balancing and maybe a battery in the future and you're good.
The handful of spots is part greenwashing part gauging the demand. They do track the usage of those spots and increase the amount if they see that they're in use and driving business.
