Most designed product?

Which product do you think is the subject of "redesign", or "concept" or "i know how to do that better".
Its childrens buggies. Strange is it may seem, this is the one that most "would-be" design graduates decide to tinker with. The one they feel has the most scope for change.

Why is it that the humble "pushchair" or "stroller" is the target for the next generation of creative engineers.
Is it that it is a product we all identify with, as we were all children once?
Is it that by improving its use, storage, and look psychologically means that we are "giving back" and helping those that helped us be who we are i.e. parents.
Is it the combination of mechanisms, upholstery, materials that tap into the engineers psyche.
Is it that the potential market is guaranteed, and constantly increasing, i.e. children.
Is it the "transformer" figure for adults, ideally morphing from an "all terrain" vehicle into something the size of a sugar cube.

Are they, that we see them everyday, even when we're older, and our mind starts "inventing". When we drift into that "daydream moment".....

The women in the bus queue struggling desperately to fold down the contraption, laden with 3 bags of shopping and small children, before the bus pulls away, to then climb aboard and have to find the equivalent of another chair space to store it discreetly.
The dad in the supermarket car park, who we have spotted walking back to his car, and whose space we want, rapidly loading his shopping. To then spend and age collapsing the modern equivalent of the beach deckchair.

The current headlines regarding the maclaren buggy guillotining small childrens fingers, shows however, that for all of the looks, feel, comfort, colour, size, weight, and name of a product, it is function that cannot be overlooked or taken for granted.
Complacency is a competitors dream.
