I don't know, a lot of these things seem to have analogs to human drivers.

I can cause emergency braking on the road outside my house by behaving like I'm about to run into the street while never leaving the sidewalk.

I could get on an overpass and shine a bright spotlight in drivers' eyes at night.

I get what the author is saying, and there will be a continual need to improve self driving cars. Sure there may be different ways to troll them, but I don't think he makes a strong case that they will be particularly more troll-able than humans.
