1. Quite a few out there, and the evidence is looking good that modern batteries will last as long or longer than gas engines.
2. And there are mobile chargers, not in circulation yet. But there are tens of thousands in use in cold climates and we've not lost anyone yet. Remember, most EV owners top up every night so odds are good that they have more "fuel" than the averager gas car around them.
3. Why look, only three posts up, recycling!!!! Whoda thunk, massive batteries are easier to recycle and worth the effort, unlike billions of cellphones and laptops.
Looks like there are two Superchargers on the way to Norfolk, right across the bridge in King George, and Tappahannock, although at around 190 miles, you wouldn't need to charge in a long range Model 3 (310 mile range) . In the regular range (272) , it suggests a 10 minute top off at Tappahannock. You could be trapped on the road for days and keep the cabin at 70 degrees and watch Netflix while you wait.
