I'm clearly about safer drivers and safer cars making people using bikes safer.
However, I'm sorry to sound like an a$$, but unless you've spent the time in school and industry you really shouldn't express your opinions on impact test methodologies. The angle on the test in the video represents the fact that a person on a bike sits much higher than the hood of a car. In a crash, the head will come down at an angle. This video with a test dummy helps illustrate the angle of impact of a cyclists head on a car during an impact.
The system used in the Volvo/POC video is a modification of the EU pedestrian impact test system, this graphic also helps clarify the angle of this impact test.
