Mid engine cars have absolutely no need for such a long hood, just enough for some mechanicals like steering and some electronics but they still have decently long front ends. It's something relatively soft for pedestrians to land on.

Maybe after 100 years, that's what they settled on as the best compromise? The most efficient shape is obviously the airplane wing but someone likely won't survive being hit by one of those. You also won't be able to fit much in the back. Today's car designs are a compromise for everything after decades of trying various designs. Practicality, safety and efficiency.

I don't think you're going to see major changes to shapes of cars change until there's massive advancements in material sciences. What propels it isn't big enough of a change, it's still a big hunk of metal. Being electric can arguably more dangerous because there's a lot more mass carrying more momentum making it harder to stop quickly.
