This is also literally not true. Currently shows 7/10 free and Tesla’s own historical chart shows that it’s never above 50% today.The Supercharger there has been designated as "congested" continuously for literally years
Now, take a charger in the middle of SLC, and it’s a completely different story as expected. Only time it’s not considered congested is after 9 pm and before 8 am. Nothing surprising there.
