suspension is as much art as science, and drivers have never been educated how it works.It's basically that the feedback loop (IMHO) is broken. As long as Tesla keeps getting sales and sales growth (or there isn't sustained massive bad PR or is depressing their stock price), they have seem to have little incentive/motivation to address some of the very basic things Fourdoor brought up that MANY other lower end/cheaper vehicles have and have had for ages.
If enough people vote w/their wallet and feet and Tesla figures out that those missing things will reverse the slide/fix problems with PR or stock price, things might change.
And, Tesla/Elon are all about hype. Those things aren't really hype-worthy or sexy. So, instead, they will come out w/something else shiny then hype it, get fanboys, the public, Wall Street, etc. all spun up about it instead.
your comments are spot on. but don't expect the fanboys and subjective opinions to meet yours even half way. welcome to the internet.
personally I find the MY suspension mediocre... but I know how to fix it, without breaking the bank. I raced cars and educated my assometer over 10 years.
