Answer:
If all automobiles and electronics vanished my life would change in multiple ways. For most people, our lives revolve around technology. We oftentimes use it for communication and entertainment. My life would be impacted because then I would need to find other ways to talk to my friends and family, and would need to find another source of entertainment. If all automobiles would vanish then I would need to also find a different way to get around. In terms of entertainment, I would pick up a new hobbie or learn a new skill and master it. As far as automobiles go, I would use my bike, walk, or learn how to skateboard, or even pull out my good ol' rollerblades.
