You can't crawl up that, it's a lot steeper than it looks and way too slippery. Do you notice when the don't make it they always end up sliding backwards with all 4 wheels locked up, or flipping over if they bounce wrong? It's almost always on private land too.
I'm all for cool engines with tons of HP, and awesome wheeling rigs...but anybody can hop in and just floor it towards the obstacle. I like seeing some technique here and there.

I am amazed at that much detail and MONEY but no rear steer.
