What I don't like:
Single point of failure for all windows
That's where my arm rests
Could a child's finger hit the exposed tiny buttons in the slots to make the window close while leaning outside the window?
I'm guessing there isn't an actual button in there, it's just a representation of a switch? Also, current laws require the current setup (Push for down, pull for up) precisely to prevent kids accidentally rolling them up. This setup wouldn't avoid that.
This setup also means you cannot raise multiple windows simultaneously - you'd have to do one, "gear" over to the second, third, fourth. You'd also be stuck in the last position used.
Just doesn't seem very intuitive.....the application mentioned current switches are in close proximity, so you're unsure which switch you're operating. I get that, but right now if that happens, you just put the wrong one up, and slide your finger to the right one.....this would be FAR worse, requiring you to look down at the gate to move to them.
Just seems unnecessarily complex, and an answer to a question nobody asked, to me.
Furthermore, this would only be in the driver's door - do other doors have the same...eh....toggle switch for their single window? At which point, what's wrong with the current setup.
