I wonder how many pure EV owners have access to other ICE vehicles? Everyone in my circle of friends who has a Tesla, or full EV has an ICE car as well.
I have de-fleeted (!) and now have only the Morgan (which is on SORN for half the year) and the Tesla. I regularly drive 150 miles a day and have had no reliability issues and nor do I worry about having any. I have no need for back-up car, although given the reliability of ICE engines, the Tesla would actually make for a decent back-up.
With only 200 moving parts (compared to 2,500 or so in an ICE) there's not much to go wrong. The batteries will easily last 150,00 miles (rated for up to 500,000, which I don't totally believe) at which point the car will be about as valuable as my Range Rover was with the same mileage - just loose change. I'll buy another at that point and will almost certainly buy the Tesla Roadster when it launches.
It is possible to like both ICE and EV - they're not quite as polarising as some would have on here. I've owned a large number of ICE cars and really enjoy the practicality and performance of an EV.
