Costs on the road
It sure is cheaper to drive electric car even on a longer trips when you need to charge on those public charging stations. They do charge quite a premium over the price you pay for electricity at home, but the total expense is still a fraction of what you would need to pay for gas on such trips.
"Time is money" and those charging stops do take some time. Not too much to bother me. It's just a matter of being prepared for it and planning so that you leave enough time to get to your destination in time. On longer trips you would need to stop every now and then anyway for a break.
