It's funny you say that because that's the exact reason Superchargers exist. The other chargers in question charge incredibly slowly compared to a Supercharger. Teslas main advantage was that they had to foresight to realize that people wouldn't swap to electric vehicles unless they could have a similar experience to pulling up, filling up your tank, and driving off. A Supercharger is the closest thing - 0 to full in 20 to 25 minutes. The Blink/Chargepoint/WhateverElse networks are a full charge in 8 to 12 hours.
