Had a fatal recently. Speed from a yawmarks put the vehicle at 64 MPH. Hit a curb and took out two trees approx 10" in diameter. Good intrusion, 19" +/- into the engine compartment laterally. Vehicle went onto drivers side and hit another tree. Passenger space intrusion of about 37". My question is, what formula would I use to figure the speed at this point? Everything I've got talks about barriers, fixed objects etc but not how to measure when the tree snaps off. Would a basic formula work? 1.02xcrush, or whatever it is. Please help! Gotta go to court on this one and need a little extra to convince the jury of high speeds. Thanks
