I don't know why they do a light show. I think it's cool that they can do that with the cars, but it was kind of awkward. We were all just kind of standing there. Like are we supposed to be videotaping this? What are we supposed to be doing? We were all just ready to get in our cars and leave.
People worry too much about EV battery longevity. Pack replacements are expensive, of course, but so are engine replacements. And based on recent data, it seems much easier to make a battery that outlasts a car's average lifespan than an engine that can survive 250,000 miles without major repairs. Batteries made after 2015 rarely fail outright. When a battery does fail, however, that doesn't have to be the end of the road for an EV.
