Better safe than sorry is my motto. Yet flying into trees and some bridges can happen even to the best and no real way to preflight for such a thing unless you fly above all of them. Then your good for sure.
I did crash my Mini about a month after I bought it into a bridge I did not see, as it was an older trestle style bridge on a very bright sunny day. Bad glare on the phone to fully realize altitude of the drone - although knew where it was. Had hoped to fly under it, but missed it about 3-4 feet.
Crashes are almost inevitable for any drone pilot of any model. Even when being super safe, if you start practicing to go beyond your typical super safe limits - it can happen.
