I think it's more likely downvoted for the same reason the hack didn't appear on the HN home page, while hacks on Chryslers or the VW emissions scandal do, repeatedly: don't criticise Tesla.
Even when they apparently employ idiots who hook the web browser up to the brakes.
The problem is that to be able to do OTA updates, you have to have the control system hooked up to the internet in some capacity. The only way to avoid this is to airgap the 2 and make the user plug in a patch cord to update. Of course that runs into the issue of interfering with their fleet telemetry and background 'alpha test static verification'
The vulnerability has been "patched", but I cannot help but be peeved at any private automobile that can be remotely controlled. Of course, it isn't only Teslas: https://www.wired.com/2016/03/fbi-warns-car-hacking-real-ris...
