I disagree. The article concludes "Tesla's Autopilot is a great technology, perhaps the most advanced ADS on the market". What they are "trashing" seems to be the hyperbolic marketing of Tesla, which I feel at this point has been discussed ad nauseum and has gotten so much press that this just feels like a rehashing of "Tesla greatly oversold this!" that tons of people (myself included) have already commented.
It is not only marketing the criticize, also the general handling:
"In the small obstacle ‘pot hole’ scenario, all the cars tested allowed the driver to cooperatively steer and manage the situation apart from the Tesla. The Tesla system does not allow the driver to deviate from the lane centering path and will disengage when a driver inputs steering torque."
