“It hit us that these two markets have hit their inflection points,’’ O’Donovan told attendees of the summit. “What we know now is that this inflection point happens when consumers get excited around electric cars.” That point, she said, can arrive when EVs account for 10% or more of new passenger vehicle sales.
