While Toyota was raking in wheelbarrows of easy cash from moneyed buyers Nissan was selling Altimas for bottom dollar to people who were rolling in negative equity from a Dodge Journey.
This is standard BigCo stuff. You get a lead and you lose that lead because you don't jump hard enough onto the next big thing because you don't want to divert resources over the thing you're currently winning with. IBM, Boeing, Ford, Microsoft, they've all been down this road.
Nissan never had that lead so they had nothing to stop them from going into EVs deep enough to grab a good share of the market.
The Leaf can fast charge and this is now included in all models, but it can only suck down 50KW vs Tesla now being able to draw 100+KW. It also uses ChaDEMO which is a fading standard, though still very common where I live. Apparently there are some converters in the works to let the Leaf charge off CCS and perhaps even the Tesla network in the future, but they'll probably cost hundreds of dollars since apparently a DC fast charge mega-dongle is not trivial.
In other news: there is now a market for dongles for cars. I have seen the future and it has a dongle.
Newer Nissans are supposed to use the CCS standard (if Nissan gets its crap together and actually launches the Arya).
