On what routes do you travel on long? If it's Islamabad-Lahore, then it's easily doable because we have 3 charging locations now. Keep in mind the charging cost of DC chargers is high. But still many people take their EVs on long drives just to enjoy them.
Few senarios where EV makes sense.
* You have solar that produce extra units.
* Or install a separate single phase meter for EV charging only. I know a owner who is economically using his EV this way. Almost 50% cheaper than fuel.
* If you frequently travel out of city where charging stations do not exist. In this case, you should have fuel only vehicle for travelling out of city.
* If you rarely go out of city, you can keep an EV and use rent a car for out of city travelling. This will still have cost benefits in the long run due to daily savings done using EV.
Personally I never understood HEV or PHEV. I like to keep one fuel only vehicle along with EV. But in my case, I rarely go out of city. I am confused whether to keep my fuel vehicle or sell it. Because since I got my Atto, I have not used it due to cost benefits and driving pleasure.
