I had to ride in a co-worker's truck. He had rented a "heavy duty" version of the newest Dodge Ram F3500 to use for a week or so. Riding in this truck was unlike any experience I've ever had with a motor vehicle. It was like it was designed to shake you up and down as much as possible. I had never ridden in a "heavy duty" truck before, but at points I genuinely couldn't believe that a modern vehicle could shake this much on normal roads. The shaking comes as a result of the "heavy duty" design. It is supposed to be very sturdy in order to be able to tow huge loads. As a result, it is designed very rigidly (with little or no shock absorption). I rode in this car for quite a while on a round trip across town from and to the office.

During and after the trip I was thinking about the studies I heard investigated roller coasters and how their intense shaking of the passenger and high g-force accelerations can cause tbi and other related trauma. I haven't ridden roller coasters in years, but the shaky ride in this "heavy duty" truck felt exactly like how a roller coaster shook me.

Everyone on this forum knows so much more about the topic of tbi and brain injury than me, so I would like to know what everyone here thinks. Thank you for your consideration and time. Good wishes and good health to all as well.
