Unless they are talking about robot exploration of Mars traveling on these fast fusion engines, how will the inertia from that speed not kill the human passengers?

In Star Trek they had to invent a BS device called “inertial dampners” to explain why the high speed they were traveling at did not crush them into jelly in their chairs or fling them into the viewing screen when they stopped (Newton’s Law of motion) and why they did not need seat belts (and why chairs were not bolted to the floor).

It isn’t really the speed that gets you, it’s the acceleration. Right now almost all the acceleration is done in the first few minutes of travel with maybe some slingshots around other planets later to add some velocity. I assume with these they would be able to accelerate at a reasonable rate throughout the first 15 days attaining very high velocities, and then decelerate for the second half of the trip.

Let’s hope there is no sudden stops or SPLAT against the hull.

Well, if you are stopping suddenly in space it is probably because you ran into an asteroid or something. In which case the difference between 17000mph and 170000mph is academic as far as the astronauts are concerned.
