What a great test and new challenge for car manufacturers to overcome.
Particularly tough to dissipate energy in a wheel arch cavity, worst suggestion of all is for the wheel to actually come off! Mind boggles what could happen to have an intentional wheel dismount, cars swerving everywhere.
What the test can't take into account is in some circumstances you can take action like hitting the brakes. How does a heavy volvo fair in the initial speed shedding phase compared to BMW creating a different impact speed therefore a different outcome.
