I've had two electric cars. I've only charged publicly a few times. Many parking garages have installed chargers. I charge at home in my garage. I wake up every morning with a full charge. Many people who've only owned gas-powered cars don't consider this advantage.
A Nissan Leaf or a BMW i3 can only go 80 to 100 miles on the battery. But that covers the average commute of nearly every American commuter. With a charging place at work, you'd be able to swing a 70 to 100 mile daily commute and never need a public fast-charging infrastructure. If you commute more than 100 miles each direction, an EV may not be for you.

For long distance driving and fast charging, that's currently a mess. Only Tesla has a respectable offering on that front. It's worth considering that most people don't drive long distances very often.
Tesla has made a huge investment. One might speculate that their proprietary infrastructure will eventually become the standard charging network everyone is waiting for.
