Batteries in Cars, how do we not already have this feature ?

In an automobile, the Battery is basically the heart of where it all begins. Without it, a car is useless. Why is it that we still find out about dead batteries when we go out to the car one blustery morning when we are in a hurry to get to work or whatever, only to find out the battery is dead.
I mean laptops, mobile phones, flashlights, so many devices tell us when battery strength is low for cryin out loud. You'd think a person might wanna know if they were possibly gonna get stranded due to their car battery huh?? There in your laptops taskbar in the desktop screen it gives you a simple percentage. How hard would this be to do in a car?
Why do we have to find out in such a neanderthal way in a car?
It's like we decided, ok, well enough people have jumper cables so we don't need to put this feature in a car? I bet battery car sales would increase if there were such warning systems built into cars. What do you think?

Anyway, you can test an alternator by using a multimeter (provided that you can get to the alternator). Put the black lead somewhere on the engine mount. Find the power cable and put the red lead on there. The voltage should read 13 - 14 volts when the engine is running. The battery should measure the same when the vehicle is running. Batteries measure 12 - 12.5 volts when the vehicle is not running.; ▶ Reply to This
