I only use it for objects/devices that are difficult /awkward/painful to use for women, not designed for their bodies, or completely pointless- in a what a man thinks a woman needs or should use kind of sense . Like those stupid fake pockets.
See also those NoNo adverts - with a male voiceover, notice - telling women how they can get rid of the tiniest little peach-fuzz hair from their faces that everybody naturally has (even very small children) and nobody would see unless they had their face right in yours anyway. But no, it's not even mentioned that there's a product if you want or feel that you need it: it's just assumed that ugly, hairy women will realise that they must have unnaturally perfectly smooth faces - otherwise they might just as well have the facial hirsuitness of Brian Blessed and will, of course, be gruesome and hideous to anybody unlucky enough to catch sight of them.
I completely agree with the shoes one - I've frequently thought this; although I think it's the same for men's and women's shoes. Surely, the bigger your feet, the taller you're likely to be, and vice versa? Do record shops (those that still exist) have the same lack of thinking and put the Little Mix CDs in the easiest-to-reach sections right in front of you whilst the Daniel O'Donnell ones are on the bottom shelf that you have to drop right to your knees for and sit there cross-legged as you rummage through?!
I don't see the problem with phones and trolleys, though - when smaller options are available, I don't really see how you can deliberately select one of the larger ones and then complain that it's too big for you. You wouldn't do that with clothes.
That said, I do think it's down to male designers that, generally, the bigger a car is, the nicer and more luxurious it is as standard. Plenty of petite women find a little car more appropriate for them, but it doesn't mean that they don't want the smarter/comfier interior and gadgets as well. Conversely, there are probably 6'6" 19-stone farmers out there who buy a big old car to suit their stature for carting around bags of fertiliser and animal feed through muddy fields, who are baffled by all of the obligatory Star-Trek-type gadgetry it comes with by default that they have no need for whatsoever.
