we see cars nowadays,all shapes are similar,some new design is like airplane...
so, what's your idea about car's design in the future? what the cars would be like in the future?
Less easy to repair and maintain
More expensive (relatively speaking)
Unless some kind of strange reversal happens, future cars will have these traits.
All you need to do is look at the differences between cars of today and cars from the past.
You'll be able to recognize several trends over time, and these trends are not likely to reverse any time soon.
