There is risk, and then there is risk. A car isn't an investment. I'm a VR and AR headset early adopter, but there it is clear that A) newer, better models will come out long before my current units die, and B) I'm investing in my knowledge of VR/AR software development. I wouldn't be where I am today, with the job I have today, if I hadn't bought an Oculus Rift DK2 when they first became generally available. I don't have any skin in the game for electric cars, so an electric car purchase is not going to have the same impact on my life, it's purely a consumptive object. So the math becomes "will this save me money or give me more enjoyment than a similar purchase from another company".
