I'm a proponent of EVs and I'm looking forward to getting one at some point but "most" EVs don't hold a charge for over 400 miles. Many are offered with a high range option that almost meets this mark, but that's also under ideal conditions. I have several coworkers with EVs and we talk a lot about the range effects in the winter, or in hilly areas, etc.

Also you'd have to be crazy to plan out a trip that depletes your battery all the way, so that wouldn't be for a 400 mile trip.

One thing that's turning me off from EVs (currently) is the constant battling over charging standards. This creates more uncertainty than I'd like.
