I think the difference is that over time Tesla has streamlined mass production, installation, and reliable operation of their chargers.

They are averaging 1.5 charging stations installed per day over the last year in North America. Each of those stations has at least 8 chargers, some of them have 24, 40, or more.

They have moved to pre-fab construction where a row of 8 chargers are all installed in a concrete slab that can be dropped into a site and commissioned in a very short time period.

Basically nobody else is keeping up with them at charger deployment in the US and that creates a market opportunity for Tesla and a need to make some return on all of that construction by increasing utilization rates.
