I still think you've got a different definition of what a gradient is. Most of those climbs have a MAX gradient of no more than 25% at any point. Much past that is pretty much impossible (for anything other than an short sprint anyway).
Edit - Just looking at my Veloviewer numbers, I've only ever done four climbs above 25% average gradient (ignoring everything shorter than say, a minute), and none of those you would get up if you weren't either a pro, or had gearing so low that you'd take the best part of half an hour to do it.
Take these climbs in the UK, considered some of the steepest / most brutal (there are longer, but that's not the point):

I've love to see you in action if you think these climbs are nothing because they're sub 25-35%, because I can climb like few others and some of those climbs can annihilate me. I'm assuming you must have an FTP/KG of something like 6 or above?
