You can do something similar with bentonite powder. Depending on how thick you make would determine whether vehicles on pavement would have much problem. On grass, or much slope, wet bentonite is slick enough that you literally can not walk on it. A thin layer on a grass yard, wetted by a sprinkler when the time is right, and no one is going to walk up on you if they aren't wearing spikes of some type.
Just my opinion.
