So what?
Let's see them repeat the test a few times and base the results on all of the crashes.
The Free Press article cited that the BMW 5er also posted three-star passenger results. I haven't heard that "the sky is falling" about this $45-90,000 car.
As for the door opening, it didn't here. The 2nd crash may have certainly been fatal (and with a 450), but no doors opened...
Drive carefully-like it's a motorcycle. You can get killed by a car walking your doggie.
