Car got of the highway, hit a bump and got "shot" into an open field, traveled another 150 meters trough the field and then slammed into a building...
According to the traffic expert a malfunctioning ABS-system caused the trouble.

The second she got airborne, the ABS "malfunctioned" here's why:
as soon as she went airborne she proably stomped the brakes. The front wheels stopped turning despite the ABS' attempts to release them from being locked. The car still being in gear, kept the rear wheels turning. The DSC control unit saw the front being stationary and and the rears in motion and thought that the car was being stolen. If you checked the DSC fault memory (providing the module survived the impact) you will more than likely find a DWA (Drive Away Protection) fault logged in it. As soon as the fault logged, DSC ceased to function. I've seen this fault get logged while i have a car up in the air with the rear wheels turning despite the DSC being switched off so the wheels can turn.
Since the M3 in question was not a convertible, it didn't have a negative g force sensor on it to trigger the RPS, the MRS module didn't shut off the fuel pump to shut the car down when it landed. The fuel pump didn't get shut off until the thorax bags blew when she struck the building.
An unfortnate series of events. RIP to the mother and child, and my condolances to the rest of the family.
*edit*
In taking a closer look at the pictures , the car was a convertible and the RPS did deploy(look at the black bars sticking out of the rear head rests)
The fuel pump should have been shut down prior to impact, but i could be mistaken..its possible that the RPS doesn't trigger the MRS mole to shut down the pump. I'll have to look at my information on the E46 Roll-over Protection again to make sure.
In any case, she was hauling some major ass to have left that long of a skid mark. Maybe it's just the picture, but i can't even see the highway.
I'd say "natural selection", but it's a shame her daughter died with her too.
) and the SMG (if so equipped) modules will go into failsafe because they all need to communicate over a CAN line. Should the CAN go down, then the DSC cannot transmit an engine torque reduction request to the DME to back off throttle opening, Which is partly what was going on when the cars were on the dyno. the DSC would interpret the difference in wheel speeds and tell the DME to back off the throttle so that the wheels could catch traction.
