Humans are very good at quickly getting objects in and out of awkward spaces but only if those objects are fairly light. Your AA batteries are no problem for even a small child to handle. The starter batteries for petrol powered cars are getting towards the limit of what one person can easily and safely handle.
Afaict an electric car battery is of the order of half a ton. Getting something that weight in and out quickly while also keeping it in a place that is sheilded from crashes and doesn't mess with the praciticality or aerodynamics of the car is a much trickier proposition than dealing with a few AAs.
