That's true today. But within 2 years, almost all mainstream EVs will charge quickly. I base this on the experience Tesla, Ford and VW customers are rapidly gaining with HVDC charging and the speed at which Electrify America is getting built out. In two years the only market for EVs that don't have a fast-charge option will be ultra low-cost urban commuter cars. And even then I'm doubtful; cars that can only charge with HVDC might even be cheaper since they don't need an onboard AC/DC converter. Couple that with economies of scale and the car companies might just decide slow-charging cars don't make sense to build.
