What is the future problem of planes?

Can planes replace cars very soon?

There may be two problems for plane makers to solve.  The era of flying is real if these problems are solved.

Problem 1

Planes will be much bigger than cars.   They will be lighter but the space they need will be much bigger.  They will require a relatively large amount of space.  You have trouble to locate your plane after your dinner.   You will find the city is too small for planes.   It will have a better use in remote villages, not cities.   Can you fly back to your home in multistory buildings?

Problem 2

You need to use a plane without electricity,  like birds.

That means you need to do away propellers.

This is the real problem provided by heavens, not humans.   The dream of flying is still a remote dream.  But it is stimulating.

Can humans invent something to replace electricity?   Can humans use muscles to fly and not use electrics to propel?

It is a real challenge for our future.
