Scala : Why can't we do super.val?

Question

I am practicing this code from JavaTpoint for learning inheritance in Scala. But I cannot access the member Bike from the class Vehicle who\'s value is initialized to zero.

Answers to similar questions here overriding-vals-in-scala, or here cannot-use-super-when-overriding-values say: Scala compiler does not allow to use super on a val

Why is that? Discussion in last link above points to: SI-899. And the first comment there says following: it was changed so that traits could override vals to be more uniform with classes
