EDIT: lol Stu beat me to it. The battery wasnt already installed. If it was I could see it being a common sense issue.
The hood release says pull. U pull it. Wasnt the hood already on the car before pulling the hood release? If u remove the hood completely...THATS not having common sense.
Ppl pulled the tab before putting the battery in. With no indication it was for removing the battery, some folks removed it completely. Like someone mentioned at another site, the tab was too ambiguous. Its clearer now. If u remove it all the way NOW, not having common sense comes into play.
Evolution, I was one of the ones that almost pulled it out, then decided to put my battery in first just to see what happened. Me coming from the Droid, that didnt have a pull tab, I woulda been more inclined to pull the tab all the way out. I woulda assumed removing the battery was gonna be the same for the X.
I can see where u coming from about common sense. But I dont think the folks who did pull it all the way out dont have common sense tho. Common sense also says follow directions, pull the tab cuz thats what it says. Especially with the battery not being installed I can see why some pulled the tab all the way out.
