Dead on with this observation. I know a lot of EV adopters are more hippies and are largely deluded about the eco-friendly aspect of EV's. They're no saints. They do throw less pollutants into the environment at the place they're being used, but the tradeoff is battery mfg is nasty.
For us...
electric motor whine is universal. The one that drives me bonkers is Toyota/Honda/Nissan's backup warning that sounds like metal grinding apart as they reverse. Our Kia has a beeper. And the motor whine to me isn't terrible.
All cars looking the same is not unique to EV's. Been that way for a while.
But to answer a bit more deeply,
Go sit in / drive a model 3/x/y. Then go sit in /drive ANY other electric vehicle in the same price range on sale from an established auto maker. The differences are very apparent...
I'm not a fan of Tesla designs in general. I respect the innovation and the technology the engineering teams are producing, and I think it's a net positive benefit. But they need to focus on developing tech and let actual car makers handle the "building the cars" part.
