there also was a passenger - you see, the right side bags deployed, the main bag, the curtain and the door bag... and the door open (assuming that the door was opened by the occupant... both of them wore seatbelts (which is VERY strange in russia), which makes me think, he was racing and not just simply drunk - he prepared for a possible crush. the windshield is intact. however, on the other hand, since there is some blood on the passenger bag, there is a cnahce that the passenger did not have a belt on and missed the windshield because the bag stopped him... and the indentation on the steering wheel may have been caused by the driver's forehead - in that case, he did not have seatbelt on either. those are the things that the investigation needs to cover to recreate some of the pre-impact history..

the steering wheel should not have shifted to a side, it should have collapsed AFTER the bag deployment, if it was going to deform in the first place, to protect the driver.
the iDrive knob is laying by the brake pedal, or at least there is something round there... the trunk is opened, not sure if it opens in case of impact, if it was opened by the driver, or it was opened by the field officers...
it seems that there is cell phone by the gear selector? the cigarette pack on the floor would have fingerprints on the plastic wrapper that can be beneficial in looking up the driver or the passenger (of course, the registered owner need to establish if the car was stolen, driven by power of attorney, or whatever)
what about the car DVRs on other vehicles, were there any? are there any injuries from the other parties?
