We had the same fear "range anxiety" but once you get you make it work! We don't do long distance travels anymore to KZN or CPT like mentioned that is a plane trip, besides I have 3 kids all of them on anything more than a 2 hour trip is actually what gives me anxiety.
The best thing for buying an EV is to wait for nice low mileage unit that has come down tremendously in price, up on auto trader there is a 2022 Audi RS E-Tron GT going for way less than half the retail price(edit* I maybe wrong on price but I saw some ridiculous figures on cars.co.za) with an option to extend plan to 2037 for R77 000! Now this is a monster of an EV based on the Taycan platform and it looks the part too!
Sad to say but EV values tank a lot after the first owner.... If you venturing into an EV just consider where your usual "charge" spots maybe within your immediate area and the commute to work, in addition install at least a 7 to 11kw AC charger at home, a plug charger (2 to 3kw) if you want to top up from your solar system. If you want to charge at 7kw from solar than you need a huge solar array because that 7kw alone goes to the EV, what about your home loads ? I have this discussion a lot with my customers.
Volvo's are also good buys, then there is BYD, Merc, Audio and BMW all come in at a high price when new... BMW are giving deals at 1% interest on select EVs, why ? Because they are simply not selling fast enough so if you shop around you can get good value out of an EV, in addition to that you get R10 000 charge card from grid cars when buying a BMW EV, a wall charger( which they arrange to be installed) as well as a standard plug charger (this should be the norm for most brands).

@m0lt3n said if you want it to work it "will" work!
