It really depends on how you're using it. That Fiat has a really short range and a pretty slow charge speed. It's not for traveling like you do, it's for runs to the store in a city. On the other end, something longer range 300+ miles like a Tesla, or some of the GMs and Hyundai/Kias, they make great touring vehicles. Just look for a charging spot near your destination or most highways in the US have rapid charging now.
Now, public charging is usually not cheaper per mile than gas. If you're doing is to save money, an EV and relying solely on public charging nets out to the same as a similarly size gasoline vehicle, but no worse. It's pretty much just equal on fueling costs. The EV pulls ahead slightly on maintenance costs, but probably not enough to justify a purchase in either direction.(*this is assuming US electric and gasoline prices, I don't know how the numbers shake out in the EU)
One of the areas that don't see talked about much is convenience. If you're in an area where you can charge at home and have decent public charger access, the convenience of EVs can't be beat. Just this week I had to go on a 200 mile round trip business trip. The night before I was so tired coming home I didn't stop to fill up the truck. If I had an electric, it wouldn't have mattered, but because it's gas, I had to budget extra time for stopping . If it was a Silverado EV I could have made the trip twice on a single charge. Even a Chevy Bolt would have gotten up and back no problem without stopping.
What I'm getting at is that the range anxiety is a lot more overblown these days than it should be. We're not all doing cannonball runs. We stop for food, bathroom, whatever. You can charge at most Walmarts and many grocery stores now while you shop. The only time I ever had to worry about range is when I return a rental car and they want it above a certain range before I return it.
