Can we start an Automatic Car( without an external battery) if the car's battery runs down ?

Can we start an Automatic Car( without an external battery) if the car's battery runs down ?

(OP)
I am from Mumbai India.

Last night I had gone to a function and by mistake the tail lights of my Toyota Altis remained ON.
At around 3 AM when I came out the car wont start. I dialed TOYOTA Helpline and they sent a mechanic in half an hour with an external battery who promptly started my car. Similar incidents are happening with Automatic Car users of course once in a while.The question that comes to my mind is:

a) If you are on a highway passing through thick woods or you are in a comparatively unsafe area and such problems occurs then you expose yourself to danger.
b) In such a lonely deserted place in the MANUAL GEAR cars one person can give push and other can start it by putting in gear. In extreme cases if one has some practice he can single handedly give little motion to the car with front door open and jumps in seat, press the clutch and change from neutral to first gear. But in Automatic it s not possible.
c) Cant the car manufacturers give a little thought to this problem and design some built in mechanism for such emergency situations ?

Let's think over it !

No need to make things too complicated and reinvent the wheel. Here is a link to many backup jump-start batteries:

As someone who routinely drives several hundred kilometers trips;
1) My car is kept maintained to avoid breaking down in the middle of nowhere.
2) I carry spare fluids, major hoses/patch kit, spare fan belt, and always have a jump pack onboard, along with basic tools.
I fail to see why anyone who routinely travels through remote or unsafe areas would not do the same. Even if you haven't much money, carrying secondhand emergency parts is not expensive. It's easy and cheap to carry a bottle of water, jump leads, and a basic toolkit at the very least, wherever you go. Is there really a need to reinvent the wheel here? You want to redesign the conventional automatic transmission in case someone forgets to turn their lights off.

Maybe you can find a really, really old car in decent shape.

When automatic transmissions first appeared, all of them had two hydraulic pumps.
The primary pump was driven by the engine.
The secondary pump was driven by the driveshaft, and only used when the car had to be push-started.

In the late 1950s, the secondary pumps were designed out, saving weight and considerable cost,
and nobody complained, until you arrived.

Just buy the jumpstart box.

And in those old days the parts where made so much nicer as well. No sheet steel pressed into can shapes with welded on gears, yeah the name of the game after the 50's and 60's was build em cheap and charge way more.

RE: Can we start an Automatic Car( without an external battery) if the car's battery runs down ?

But those cars with the dual pump automatics had to be moving well beyond the speed most people could push them by hand for that driveshaft pump to be useful.

If you want to be able to push-start your car then buy one with both a manual transmission and a clutch pedal.

RE: Can we start an Automatic Car( without an external battery) if the car's battery runs down ?

In the old days few people could single-handedly push the car, jump in, and pop the clutch without a downhill slope!

Yeah, but then you learned to always park on a slope. At least until you earned enough to afford a new battery...

White Paper - Design for Additive Manufacturing
With a growing number of parts manufactured directly by additive manufacturing techniques, it is important to lay down design principles suitable for such manufacturing processes and to ensure parts are designed for additive manufacturing. There are several factors that are to be considered at the design stage. Few such design issues in additive manufacturing are discussed in this paper. Download Now
