  • I didn’t yet read the article, but Tesla are in my view the simplest cars around. Electric vehicles generally, are much simpler than ICEs. The whole thing about cells is just plain wrong… all batteries bigger than 20Wh (a big smartphone) are made up of multiple cells. And the batteries are very well protected from external crashes. Thermal runaway is still something that’s being improved on them, but mainly to increase energy density and reduce the other necessary failsafes.

    (Just some napkin math: 1 lithium ion cell has around 4V of voltage, most vehicles have a 400V or 800V architecture, so you need at least 100 cells in series to reach that.)

    Edit: checked the article: a good summary of the many shady crashes Tesla is covering up, but it looks like assistive driving features and criminal handle design are the main culprits. Generally EV batteries - Tesla’s included - are really safe. But when they do burn, it’s challenging to stop it. It’s such a huge pity that the huge potential of Tesla is being run to the ground this way…
