Musk to Build Satellites in Seattle in Drive for Mars

You should read your linked page again. As far as you're concerned, the "effect of gravity" that you feel is the rotating floor perpetually coming up to meet you. If you jump, the floor keeps coming up to meet you.

I'm not sure where you got the idea that I don't comprehend that. I think it's pretty clear from what I said that I understand that.

I said:

Try jumping in a spinning cylinder in space. That's nothing like gravity.

Someone responded:

I don't see why it wouldn't be like gravity...

So that's where we are.

So, in response to why it wouldn't be like gravity, I linked to that stack exchange and said,

Because you're only being accelerated when you're in direct contact with the walls of the tube, and if you move against the direction of rotation you lose the simulated gravitational effects.

Which is true. I could have perhaps said "you lose the simulated gravitational effects in proportion to your relative velocity with the wall".

I also said:

If both of your feet lose contact with the ground, you stop being acted upon by the centrifugal force and your position relative to the ground will shift.

Which is also true. Supported by the article: A jump of 1m/s (equivalent to a ~5cm jump on Earth) would displace you 13cm on the centrifugally rotating station. To reiterate: A 5cm Earth jump would result in a 13cm displacement. It would also result in an apparent jump height on the station of around 1 meter. That's pretty huge. That's a totally different experience from gravity. Note, however, that the amount of force imparted into your body from the ground pushing up at you in this case would actually be slightly larger than 1g if you were continuously in contact with the ground. So you'd experience, in terms of weight, slightly over 1g of gravity, but could jump 1m with the force necessary on Earth to jump 5-6cm.

A good dash and jump against the direction of the rotation and you're basically weightless/drifting unless you grab onto something.

Which is also true. Not easy, but (I think) doable with a running jump if you're fairly athletic. I don't think a straight up high jump (which would require enough force to jump straight up 1.24 meters on Earth) or a straight run could do it, but a running jump? I think that's doable.

The point was to illustrate how different it is from gravity, though.

Also, no matter what gravity is, neither you nor anyone else is running a 2.7 minute mile.

Agreed. I said that for purposes of illustration with regards to how different it is from gravity, not because I think it's achievable.

Riding a bike, though...

Anyway, in conclusion: I stand by my statement that centrifugal force would be way, way different from gravity. And I think this should be blindingly clear.
