Regarding charging infrastructure, have you seen this map lately?

If you don't have the ability to charge at home (condo or apartment), the idea of waiting at some energy pump for 30 minutes every morning is the opposite of alluring.
I've seen plenty of $35k+ cars in ghetto apartment housing. People seem to look at the monthly payment instead of the total cost of the car can never seem to get enough saved to buy a house.
I don't know which is the main buyer of higher end cars, but they shouldn't completely discount people who prefer to buy cars than save for houses.
As I stated, you will have trouble charging at a condo. In the bay area, most new development is condos, and I don't think buying one means you're bad with money.
US is the richest and most car friendly nation of the world. There aren't many countries in the world who can afford a $50,000 car especially when there are poor charging infrastructure.
