Here's the current map of CCS (400KW) chargers just from the VW subsidiary Electrify America (top) and Tesla's Superchargers (bottom). Yes, there are still large areas of the country not covered by high speed chargers but all the high traffic interstates are now covered. Stations on these two maps all have sub-30 minute charging times and are all connected to travel plazas or shopping areas so you're not standing at your car the entire time. EA's stated goal is no more than 50 miles between stations. Tesla tends towards 75 to 80 miles between interstate superchargers.The Volt is one thing, but an all electric vehicle is another.
When one drives up to 250 miles a day, and is still on call that could result in up to an additional 120 miles of driving after work hours, how would an EV work out?
Not so well.
It doesn't get me from NY to Florida and back very well either. No thanks.

Tesla Supercharging Network
In addition to EA and Tesla, there are additional charging networks, ChargePoint, EVGo, etc. that have sprung up to handle medium speed charging in our cities. By medium speed I mean 25 to 50 miles of charge per hour. These stations are almost all in shopping center and restaurant parking lots so you charge while you shop or dine.
