In Chicago area for anyone wondering using the Walmart charging network. This is about ~13% capacity, wasn't really low started charging at about 70%.
The only thing I would add to Dogyote's EV math is a lot of states (like Ohio) charge extra for EV registration ($200 more in Ohio). So if you drive an average of 12,000 miles per year, that extra registration fee account for an additional 1.667 cents per mile. But its still 10 cents cheaper per mile vs gas. Gas would have to cost less than $2 to compete price wise.
