thecarchik submits this interesting bit of flame: "Many are keen on the concept of open source electric cars — that is, electric cars where the built-in software can be tweaked, parameters can be changed, and in theory, the cars can be improved. Only it's a really, really bad idea. ... Even carmakers themselves have trouble with software — Fisker has issued a recall and apology recently with its Karma — so allowing average Joe to tweak the car's inner workings seems like a bad idea. Changing the characteristics of an electric car isn't as simple as re-jetting the carbs or swopping out the air filter."
Whether software is controlling electric
cars or not seems to me beside the point; access to the underlying software doesn't guarantee improvements, but blocking access to it doesn't stop car makers from making software mistakes — it only ensures that those few interested hackers who might be able to work around them have a harder time of it. (Not that tweaking car software
is new, or going away.)
