It’s all about hope. The same reason people buy lottery tickets.
The problem is also that there really isn’t anything better to buy that would be available sooner. It’s a lot easier to move the goal posts for a few more months than to put a deposit down on something like a Rivian and possibly wait years. Maybe someone could find an EQS, but that would seem anti-climactic after test driving a GT. Plus, it looks like an upside down bathtub to quote a forum member. I’ve pondered getting a Taycan, but that range is a non-starter. Tesla? Fugedabouditt. So, move the goal post and wait it is.
