After nearly 3 years with my Clarity, which I consider an engineering marvel and amazing integration of complex systems, there are a couple of items that stand out. The lack of a fast (DC charging) option that the all-electric Clarity has reduces long-distance driving to 200 mile range gas stops to fill the 7 gallon tank. This reduces mpg to the 30-40 range, impressively maintained given the vehicle weight and complex drive system but the least efficient mode available. I don't know if space or cost were the limiting factors, Honda of course is defensive (use gas mode) but a retrofit or design change would improve the car value and efficiency dramatically. The other (and obvious) requirement: 240v home charging available 24x7. I couldn't install a "charger" without a service entrance upgrade so relied on a public charging array 2 blocks away. Between overstay tickets, punitive rate changes (24c to $5 hour starting hour 5) to chargers down I've lost trust in the infrastructure controled by private companies with their own agendas: since these are utility extensions they need regulation. Incentives need to push manufactures to include fast DC charging in all electrified vehicles and cities, counties, and states should mandate minimum DC fast charger inclusion, stop price gouging by charging networks and regulate accessible and maintained locations. California and other states that have long stretches of freeway should add charging stations at rest areas or extend existing facilities in partnership with charging networks. State-compliant locations could add a small tax (< 5% ) to recoup lost gasoline taxes that fund highways. 240v AC charging are impractical for 200+ mile trips, fast DC charging is the answer.
