Considering any new electric cars you buy would have to be made from materials mined and processed, manufactured into a vehicle and then shipped long distances before it even gets to you, keeping your existing car and maintaining it well is possibly better for the environment when the entire life cycle is considered.
But that would require caring enough to put the effort into deleting the account.
I’d rather just leave my account unused and taking up space. Then I don’t have to visit the site.
