Scheduled ignition/warm up

By Jude A.

What if there is an on board computer that starts your car and warms it up in the winter before you get in it to go to work or if you are on vacation it will warm it up for you so the battery won't run down. about the car with dual engine ,the two engines will have to be small small or small or medium  and fitted like on a smart or a Toyota yaris  or scion, ford small cars so that it will have a trunk too .the fuel tank should be large enough to equal for both engines because you are driving two cars in one.
