It depends on the model of EV you're looking at. Generally, a rapid charger (like those usually found at motorway services) will add about 80% charge in around 40 minutes. It probably comes down to how often you plan to do such journeys. If you can charge a car at home and rarely travel more than 100 or so miles a day, an EV makes a lot of sense. If you're a high-mileage driver, regularly covering 300+ miles a day, it takes a bit more commitment (although it's certainly doable). If you're hesitant, have you considered a hybrid or plug-in hybrid car as as kind of stepping stone? The latter will be able to cover local journeys under electric power alone, but has a petrol engine on hand for when you wish to travel further afield.
