As part of prepping the vehicles, each vehicle was weighed. A spreadsheet comparing the actual weighed vehicle weights to the weights for the vehicles in Expert AutoStats can be downloaded here

Weight Comparison - Actual vs Expert Autostats

As  part of our documentation of the scenes, both scenes were scanned, twice, using Recon-3D on an iPhone 15 Pro Max. A write up of the time and "Error Rate" was prepared due to a number of people asking me about how long, how do the scnes look, how accurate, etc.

As part of the Crash Test Data review a Force Balance analysis was prepared for Crash Test 2. An expanded write up of the considerations, problems, and methods was prepared and is available for review.

Crash Test 2 - Force Balance Analysis "Write Up"

Compilation Video - CT1
The IPTM Symposium Crash Testing was conducted on May 18 this year. This year, the "theme" was "Unusual Collisions without EDR/CDR support"


To that end, the first test (CT1) had a Honda Accord Sedan stopped, with a motorcycle stopped behind it, similar to what you would see at a Traffic Signal. The Rear of the Motorcycle was about 12 feet behind the Accords Rear bumper.


Then, along comes our "Hero" in a Ford Explorer, probably on his cell phone, and hit the rear of the motorcycle driving it into the Honda while traveling at about 58-60 mph.

Compilation Video - CT2
The IPTM Symposium Crash Testing was conducted on May 18 this year. This year, the "theme" was "Unusual Collisions without EDR/CDR support"

To that end, t
he second test (CT2) had a Jaguar XK8 Convertible stopped in a configuaration perpindicular to the path of an oncoming Dodge Avenger. This is similar to a vehicle that started to pull out into an intersection from a stop sign, and then had to come to a stop in the lane of traffic, most probably due to a pedestrian crossing the intersection in front of them.

The Dodge Avenger hit the Jaguar XK8 over the left rear axle  while traveling at about 66-68 mph.
