Underride Collisions? No Problem with msmac3D!

Underrides? No problem with msmac3D . Below is a sample answer to the question: did the trailer swing wide? or did the vehicle swerve and run under the trailer? See the video for comparison. Expect tech report to be posted soon on comparing modeling with full scale tests, etc https://youtu.be/ER7Q23...
