The other slight issue is ...you get there and someone else is using the chargers which take at least 30 mins ? Imagine waiting more than a few mins for a petrol pump to be available .....
The car tells you how busy the superchargers are... the one at Amesbury (16 miles from me) has 16 bays and is 250kW (the newest V3 Tesla chargers) - super quick and never (ever) busy. Low to full in 20 minutes or so. My nearest supercharger is 10 miles away and that has 2 stalls, not that busy and 150kW - again, super quick.
Outside of the Tesla network, charge rates are 7kW or 50kW, appreciably slower and, of course, they all have different operators requiring apps with payment cards registered. It's the wild west if you're not in a Tesla.
The range on my car is 350 miles and costs around £6 to fill up overnight. I rarely do a 350 mile trip - but if I did, there are dozens of Tesla superchargers dotted over the country.
The latest Tesla batteries are, allegedly, capable of 15,000 cycles (charges), that's around 500,000 miles. I would be very happy to get 200,000 miles out of them. My Range Rover (which I bought new) has 150,000 miles on the clock and is worth the price of two pencils. Residuals are not an issue when compared to other daily drivers - it's not a classic car.
I don't intend running out of volts whilst on the road - in the same way I wouldn't run out of petrol. They need to go on a flat bed and be taken to a charger if that happens... but the car will tell you to get to a charger and where one is. So it's very unlikely to happen unless I'm being an idiot.
I am getting on with it fine - it's quick, very easy and comfortable. You could argue it's rather underwhelming in some respects - similar to being on a first class airline seat, comfortable and easy and a little uninvolving. But for munching miles on motorways and dual carriageways, it's perfect.
