And while it is still, it is now an obstacle for other empty self driving cars. Soon the troll has blocked an entire intersection or freeway using a combination of empty boxes and other trapped self-driving cars.

You underestimate the effort a good troll would be willing to put into this.

There are lots of simple things that one could do to a roadway to impede or endanger traffic. Consider, for example, the danger of leaving something sharp or slick on a tight turn where people often speed.

I've thought about this for a few years, and as near as I can tell it's either much harder than it seems, or there are fewer vandals than I'd have expected.
