Whenever I hear anything
Whenever I hear anything about battery breakthroughs I think of this Accord hybrid. Imagine if battery prices came down by 50% and also became more dense by 50% (same size, twice the range, half the cost). It would be cars like this that would immediately dominate the market, not full EVs. Honda, GM, Ford and Toyota combined have dozens of cars like this that could easily be converted to primarily EVs, but with basically unlimited range. The future cars are already here. They are hiding in plain sight.
