The problem with modern cars is the parasitic drain when the vehicle is not being used. I measured this on my Audi and it was about 100mA, which is 2.4A/day or 17A/week
100mA is 100mA and if it's all day it's still 100mA. You're confusing current draw with energy.
100mA draining for an hour is an energy drain of 100mAh.
So in a week you have drawn 16.8Ah.
/pedant but you did say you were an electrical engineer and this is pretty basic stuff.
