I would say that as you came to a stop you had plenty of opportunity to appraise the situation before riding over it. I think it's unreasonable to try to lay blame on the owner of the facility; it's pretty obvious it's there. I often bumped my Rocket over bigger obstacles and down gutters but never at 90 degrees and I never had a problem. It's easy, even in the photos, to see that the speed bump with that iron on top would be a problem straight on for something with the ground clearance and wheel base of an R3T. Just my opinion. Generally speaking, and I know this will upset some, I believe that people really do need to take responsibility for their actions. You saw the bump and decided to ride over it. Not unlike the truck drivers who get caught up under low bridges……….
Now if the speed bump was in a place where you'd be travelling at speed, and was unmarked with no hi vis paint etc, you might have a case.
