The initial thought was he pulled out illegally. Maybe out of favoritism, they may have assumed she was going a reasonable speed of say 60 to 65. Instead, she was driving with over 4 times the Kinetic Energy of the posted speed limit. If you physically analyze all the factors, you can roughly estimate both perspectives. She was supposedly going 107 at the time of impact, I'm going to call B.S. on that and say it's likely closer to 90. As a 107 MPH crash can easily put the engine in the trunk.
Now lets do an analysis. First her minimum slowdown distance from 113 mph to 90 is 175ft assuming she was in an 2005 Audi A4, calculated via Kinetic Energy. Her friend had enough time to scream a full sentence at her, so we can assume a HORRIBLE reaction time of 2 seconds, that equates to 113 mph * 2 seconds =~ 330 ft. Adding up her frame of reference we get that he was mostly pulled out when she was over 500 ft away. Now even the worst driver is going to peek 1 second before actually accelerating on the road, (a good driver initial peek is closer to 4 seconds left-right-left, vs left and go). Lets assume he's a bad driver and that puts her at over 600 ft away when he started pulling out. At the posted speed that's 7.4 seconds without stopping for her to reach his location, which means he should've had over 10 seconds to pull out and get up to 55mph, without her apply the brakes assuming she was going the posted limits. That's not an unreasonable pull out, and probably something he's done before on a similar road (without issue). In actuality he had 5 seconds to get to 100 mph, which is impossible.
