Aaron, I don't understand
Aaron, I don't understand your reply. The link says $1000 for the adapter when purchased for an existing Tesla with Supercharging enabled. It looks to me like it's $2400 if you order the Chademo adapter and the Supercharging HW (so $400 for the Chademo). There's no option for Chademo if you have a Tesla without Supercharging. With a LEAF, there's also no option for Chademo QC'ing unless you pay for the $1127 option package (4%).
We are so off topic here. Both brands charge $ for quick charging. Nissan has refused to license the Tesla tech, and for good reason, few LEAFs can use stations so far from home. Tesla provides a Chademo option for a price but includes (for free!) a 10kW EVSE and a J1772 adapter.
Tesla needs fewer quick chargers than other manufacturers because they have greater range. Your headline makes it sound like they're trying to achieve what Nissan has already achieved but I think you miss the point. Tesla doesn't want or need 100's of quick chargers in cities. They want them on the interstates. It's just a different model.
