You could access it through the "Driver Recorder" app in the "Apps" section of iDrive. If the video is there, you could easily export it to a usb.

As far as if it recorded something, there's an option for that within the drive recorder app, so if it's set, maybe? There has been a report or two of that not working, but that may have been user error. Unfortunately, even if that option is ticked, I think it's less likely in your case if she actually had the car in Park since all the parking sensors might be off at that point.

You might want to check with the pharmacy, if she was at the window, they likely at minimum have a camera covering the window where you might be able to see her car at a standstill prior to impact.
