From what I understand they still lead the EV space in several metrics, but other manufacturers have done a lot of catching up in the last few years. Add that to greater reliability and build quality, and inclusion of physical controls (anyone who thinks replacing the indicator/turn signal stalk with capacitive buttons is sensible has clearly never driven in the UK—my 15 minute drive into the office crosses 11 roundabouts).
Plus I've developed such a strong personal distaste for Musk over the last few years that it's hard to want to give him money, however indirectly.
