And one more thing about using a speedometer examination to determine speed, the theory being the needle gets pinned against the dial at the speed the vehicle is going when it hits the tree.... well, if your tires break traction with your foot on the gas, your speedometer indicated speed can increase even though your vehicle speed doesn't. So if you're going 70, slide into dirt, stomp on the gas instead of the brake, your speedometer immediately increases in speed. Same thing can happen with cruise control when you hydroplane. The speedometer jumps in speed. So I'd take the reference to 100mph in that accident as just another data point to consider in the overall accident investigation. If the vehicle had a computer, that would most likely be more accurate, as would skid-mark analysis, weight of vehicle, etc...
