The field drawings spec the scoring areas as a sheet of 1/2" plywood on top 3 strips of (3/4" plywood + 1/2" plywood). That whole plywood platform gets stuck to the carpet with 2 long strips of 2" velcro. The HPDE gets velcroed to the top of the 1/2" sheet and the ramps are velcroed to a short bevel on the edge of the sheet. It looks like the bottom edge of the ramps isn't velcroed to the carpet. The ramps are definitely only supported by the carpet at the bottom and the velcro/plywood at the top.

Anyways, the 2 strips of velcro will probably provide enough grip that the only way you're really moving things is if you move the carpet. I'd be more worried about how the 1/4" thick HDPE ramp is going to react if you hit it at high speed. It's a 7" long span only pinned at the ends, so if you hit it fast enough, you'll probably deflect it a bit, which might make the ride over the bump a little rougher than at slower speeds.
