Apartment complexes where I live (Denver metro) are already competing with each other on features like "bike/snowboard fix-up stations", "Amazon lockers", "heated pool", and other absurdities - you bet they're going to install 220v chargers if it helps lure people in. Eventually, it will be expected - just like the bike fix-up station.
If I could buy something equivalent to my current car that was electric, I’d be happy to. But I would definitely have to figure out the charging situation. And that could easily turn into a mess. That mass, plus premium price, plus possibly limited availability may make it easier for me to just buy another gas car for now.
*Number made up
For example, if electric cars become popular we will need tons of public charging stations, but nobody will be willing to build charging stations unless there are already a lot of electric car owners to use them.
The early adopters of electric cars are going to have to deal with a lot of overcrowding at charging stations, unless they are homeowners and can charge in their garages.
All that aside, there is still the issue of price. I paid $21k for a new Prius C that gets 45-50 mpg. A new Chevy Bolt costs about $29k in California after tax credits as far as I can tell, and that does not include the cost of an in-home charger. That $8k difference would cover years of gas purchases for the Prius -- I've had it for 5 years and I've been spending about $35 for a tank every 3 weeks.
Unfortunately that little piece of infrastructure could easily be a deal killer for a ton of people.
Not everyone is a homeowner with a garage. And parking in a charging space at some random retail establishment every couple days for a few hours to charge just seems insane.
