git's wall is thick, made of brick and reinforced concrete, and you'll be heading toward it at 200kph. You'll get going again eventually, once the metaphoric car gets glued back together.
Non-metaphorically, my experience has been that with SVN, Mercurial, et. al., a few quick web searches and I'm on my way. With git, "wait a minute...run that by me again?" I've used git for going on a decade, and now that I'm in an SVN shop I do sorely miss it. But, man, it's got some sharp edges.
Up until this day navigating code feels more natural on the site that on native apps like sourcetree. I really miss the ease to see the same file from two different branches or commits, the feature might be there in native apps but I just couldn’t find it.
I know, right? This 'evil' thing is going places.
