While I appreciate the article I wish the author had done a bit more research, a lot of these are straightforward questions that can be answered with just a little digging.
[Range anxiety, the fear of getting stranded, which happened to me with the very first electric car I ever reviewed. This is a real fear for some people, especially if an electric car is all you own. Today, most can go 60-100 miles before needing to be charged, with a couple of vehicles getting between 200-300 miles.]
I'm pretty sure we're going to see 250mi+ as the standard moving forward with the Bolt, Model 3.
[What effect does weather have on my range? Hot and cold weather can have a very adverse affect on battery life.]
~10% give or take actual air density. This is in sub-freezing temperatures at highways speeds. Yes you have to plan for it a bit but not a problem with the answer to the next question.
[Chargers. Other than home, how many chargers are going to be available? Will they be the quick chargers, or the ones that take many hours? What will it cost me to charge my car when it is at home?]
If you have a Tesla, tons. Specifically 18,000 by the end of 2018. This is one area where I think Tesla dominates other companies and I agree that without this you don't have nearly as compelling of a vehicle.
[How will we ever dispose of all the batteries once they start going bad? How much can be recycled from a battery pack, if any, and will they just end up filling landfills?]
Easily, recycle or reuse them in stationary power. Tesla has been doing this profitably since '11
Tesla's Closed Loop Battery Recycling Program | Tesla .
[What happens to our already poor roads and highways? All these electric cars will cut down on gas consumption. Today, 18.4 cents per gallon of gas, and 24.4 cents per gallon of diesel go straight to the Federal Highway Trust Fund. There is also on average 30 more cents per gallon of gas and diesel that goes to state and local roads.]
This is already getting addressed. Here in WA we have a $150 EV tax on title registration. That was actually more than I used to pay in gas tax with my previous vehicle. This isn't a hard problem to solve, EVs should be paying their fair share(or more) of the road tax.
