When exiting the slide at 26+ MPH on to tarmac is the best hoped for outcome compared to falling off the side on the way down, it looks pretty bad
Helmet and full inline skating protection gear highly recommended (wrist, knee elbow, maybe even hip pads for us older folks).
Me, I feel much safer sliding down snow and ice slopes in the mountains -- I'm allowed to bring my ice axe to slow down with
More seriously the upper deck slides will need a deceleration pad at the bottom
