Why can't some car-related issues be fixed just by adding more of the same parts?

For example, why can't more 12v batteries just be thrown into the engine bay and running into a higher-level step-down transformer or something like that? I feel with three or maybe even two, running out of AC power outside of engine feed would probably not be much of a worry.

    How do you think your going to get ac out of a battery?

    Why would the car need more battery's anyway?

    Another moron that thinks it can design concepts that has no idea how things work.

    No matter how many batteries you put into a car- they will never produce AC power by themselves.

    For those of us who need some AC power out side of the engine feed- we buy a power invertor. No more batteries are needed, maybe a bigger alternator.

    I suppose pulsing a light beam will  make the beam  "stop" at 3 feet for a Light Saber, Too?

    You can but WHY?  It is "dead" lead weight.  You can get a 740CCA battery and so long as the engine is running and the alternator is charging(a red idiot light shows up on the dash with the word "BAT" or "GEN"...when it lights up increase the idle speed to kill the light so it is charging.  Too slow an idle turns on the warning light.  That is the way it works. A.C. needs a hot motor...to work.

    The simple answer is weight, cost & complexity

    My truck and camper had TWO batteries to supply the extra electrical needs while parked.You can wire the batteries in parallel simple to do and no need for some transformer,voltage regulator thing.

    Transformers is not what is required for extra battery storage capacity.

    Transformers do not operate on DC current. All problems aren't electrical and all electrical problems aren't deficiency. You way of thinking isn't considering mechanical relationships parts have with each other in the machine. There may be issues where a car needs more electrical power, but those issues are created by the owner, not the engineer who designed the car to work fine the way it comes from the factory.

    So you would like to have back up for all the parts.  Like having 2 or 3 transmissions in case there is a problem with the original.  (?)  And we should keep the car small, economical to buy and get good gas mileage ?   

         Lots of cars do not even carry a spare tire any more, because the ones on the car are so reliable.  Great Grandpa had a car with 2 spare tires (one on each fender) and expected to use them on any trip.

    You might have something there. A lot of cars' most serious issues can be solved by adding a couple more pistons.
