Terminal velocity is around 120 mph?

I see where it takes a lot of stories or maybe around 1,500 feet to get there to tv. We have a boat that will run a little over 100 mph and a concrete bridge that is solid rock all the way across. Of course, cars will run 120mph. I have known jumpers that jump from say 15-20 stories are getting nowhere close to this on their jumps. Makes me wonder if the boat that goes fast or a car would be a better option than jumping.

Not 100% sure what the "essence" of your post is trying to get at, and I apologize if I'm misunderstanding it, but it seems like you're making the inference that Terminal Velocity somehow equates to "assured" death. The word "Terminal" in the term Terminal Velocity has nothing to do with guaranteed death, although crashing at speed that fast could certainly lead to death. You could easily die at half that speed, also.

Terminal velocity is the maximum speed attainable by an object as it falls through a fluid (air is the most common example). It is reached when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object.

There's a huge difference between crashing against an object/surface at 120 MPH and crashing against an object/surface at 120 MPH inside a vehicle.

There are a lot of factors involved in a vehicle crash, but the most basic one is that the impact will be absorbed first by the vehicle when it touches what it's crashing against and only then will the impact be passed onto you. Maybe you're thrown clear off the boat and land legs first in the water, maybe the car is modern enough for the energy-absorbing structures in the chassis to save your life. Maybe it's got an airbag, if it's a boat that fast then it's probably long and sleek so that's a lot of fiberglass between you and what you're crashing into.

Simpler is the way to go.

Those are valid points. In my mind i was equating speed with a successful ctb. Nearly impossible to get to 120mph by jumping but easier to get there by propulsion.

Absolutely it is. And many people die each year in 60 mph crashes, even less. Maybe they're just lucky, though.
