I have a Honda Clarity. 48 mile range, though I only charge it to 90%.
I've gone 15,000 miles now on about 30 gallons of gas. I keep trying to get over "500 miles to the gallon" but that's a limit I have a hard time surpassing: occasional long trips or forgetting to charge does me in.
(Not to mention the car will occasionally burn gas on its own just to confirm the engine is in good working order).
It seems like it would be a waste for me to have a 200-300 mile range and no engine. The longest trips would still have been less convenient. And you could build 4-7 cars like mine with the same battery resources.
No, because stop-and-go gets the most benefit from regeneration. One full EV for one long commuter who also drives around town, or 7 PHEVs for people that commute shorter but also drive around town.
Long haul stuff should probably be transitioned last both with commuting and things like trucking (stop and go things like trash and delivery and bus service makes a lot more sense than targeting cross-country trucking first).
