One big problem is that cars exiting cannot see round the wall to check for pedestrians about to cross - and pedestrians cannot see either, especially if they are pushing a pram. It is very dangerous.
Of course there are more pedestrians crossing the car par exit since they removed the much loved Perry Vale island crossing further up.....
The answer is obvious to all - build a nice wide pavement around this blind corner leading up the slope, and remove the pointless central partition.
I rather optimistically assumed that raising the pavement level here was the first step in creating a less steep paved entrance to the car park or even platform 2.
