With the rare exception for when the expected marketing value of having those spots or tax subsidies make installing them appear to have a positive value. The exception that definitely proves the rule. Until it's mandatory in new construction it won't even start to become normal. I'm curious how street parking is supposed to work, that photo is hilarious but I imagine that on the streets of Boston where you'll get hit with a bat over trying to save a parking spot (or trying to use a saved parking spot, it's Boston in the winter). I have the feeling you're going to see better adoption in suburbs and lower density urban areas first because the range doesn't need to be so high but it's also not impossible to have a consistent parking space (or garage or driveway) that you can invest in improving. I'd probably have to get a special variance from the city to install an outlet in the sidewalk...
