A bit of a naive question I admit, but how do you even test hundreds millions of lines of code to ensure they all fit perfectly when different ECUs have different suppliers, and by customizing the car you can have different types of chips? Just curious how integration of all the components is done.
Also, there seem to be a lot of recalls due to software issues, so I wonder if there's any open source or anything close to it that has tools such as CI or VCS for newer electric car companies that use ECUs from different OEMs?
