Just on the "fuel" cost, as others have mentioned, you do most of your charging at home, at very low cost.
If you have an off-peak power plan, it works out at less than $2 per 100 kms of driving. Even less if you have excess solar.
For road trips your first "tank" is from home. You then use Superchargers, which are more expensive, but still cheaper than petrol, or charge at your hotel/motel which is often complimentary.
As for the general driving experience, theres no engine drone so you can do long stints at highway speeds and feel fresher on arrival. Conversation is easier. Music sounds better. Overtaking is effortless and stress free as mentioned previously. If you wish, the car can do much of the driving itself, or you can be fully manual, or in between. If you want to do some spirited driving on a twisty road, you can do that too.
This is our family's only car, so we're all-in. If I struck some extreme edge case like needing to drive to birdsville, I'd rent a car.
It would of course be a more difficult decision in places like WA where there are few if any superchargers AFAIK. Also more challenging if you don't have access to off street parking at home.
Further to the earlier discussion about setting charging limits, such as 80% for daily use or 100% for road trips, this is done via the app or the screen in the car and is simple as sliding your thumb:
