For reference of where the car was parked originally -- it was about where the police cruiser is in the last picture.
That girl was definitely going over 25 mph when she hit the car... that's a pretty good run considering she had only made it 150 yards up the street.
Ok, so my inner nerd came out to see if we could calculate how fast she was going. Looking at your video, the only relatively accurate distance i could see was your neighbors driveway. the average width of a driveway is 12 foot. using a stop watch, i averaged out how fast it took her to go the width of the driveway -- avg was .31667 seconds.
12 feet / 5250 feet in a mile = .002273
.00273 / .31667 second average = .007177
.007177 * 3600 = 25.8732 mph
now if the driveway is only 2 foot wider, that puts her up to 30 mph. if you could get an accurate measurement we could get a better idea of her speed.
