Cars are like horses: people will soon realise EVs are just better, claims VW boss

This is a most excellent place for technology news and articles.
I don't own an EV either, nor do I have any financial (or otherwise) stake in any EV company or technology. Actually, I don't have any financial stake in any company, except the one I work for because they employ me, so it's in my interest... anyway, I'm getting off track.
Point is, on your road trip, you had to stop for food. The idea is, you'd refill and eat at the same time. Unless you were really picky about your food, you could just eat at the gas station (which also has chargers). That's the idea they're going for with these "rest area charging stations".
You make a lot of trips, which means you spend a lot in gas. Again I'm not saying you should buy an EV. What I am saying you should do is, try to find out what that trip would cost you in fuel and in charging. I bet you pay less than half for the charging. $10 vs $20 (assuming USD because you said miles) isn't nothing, but it's not a vehicle purchase decision. $100 vs $200 isn't really a purchase decision either, but it's a bit more substantial. If you had a way to figure out your fuel costs over a year and then figured out what those miles would cost to recharge in an EV, it would at the very least be some interesting numbers to look at.
