Another "jelly/fluid" that can be ran over by cars and trucks and remains its shape (mostly) is asphalt. It has been in use especially for being ran over by cars for as long as cars existed and has been in use (edit: for other things) since the fifth millennium BC. I too probably miss context, because it hardly impresses me.
