Having a battery that works ok during " normal circumstances " is all well and good but the test of a well designed system is how it copes with circumstances outside normal parameters and as we can all see the batteries regularly fail when this is the case hence this is why the small battery system is not fit for purpose.

The battery is so small that any degradation of its performance easily pushes it below its level to adequately perform that would not have happened on a larger battery. This is coupled to the fact that the car needs the small battery to run its systems and when it fails the car breaks down completely unlike a combustion car which you could possibly bump start for instance.
