Because I already know the answer. It's such a simple 3 vector sum that there's no need even to write it down.

At the very next autocross. Possibly during fun runs.....Just don't tell Amy my plan. Will you be there to watch/run your car?

Imagine this scenario.

You are in a RWD car capable of holding a consistent doughnut. attach a 4 foot rope to tow hook, at the end of which is a 1lb lead weight. Now from a standstill, initiate and hold a right hand doughnut with a constant radius.

Are you telling me that the rope will swing and hold left?

^^^thats completely different from the FD scenario. once the car begins the doughnut however, the weight should go twords the left and not the right. think of a merry-go-round, the kind you used to push each other on as a kid. now say your a kid and facing the direction the merry-go-round is going (just like the car in a doughnut). your holding a rope behind your back with a weight attached. if your buddy spins the merry-go round, which direction would the weight go? well it would go to your left and it would stay there since the left is the direction of the outside of the turn. like i said before an object will always pull to the outside of the turn. anyway you look at it the object is going to go left and not right......and somebody's gettin some beer

Justin, I think we are not on the same page.

I am trying to figure something out that goes beyond a simple, "it always does (blank)"

I'm just trying to understand how and why certain things do what they do during performance driving. I'm trying to get into suspension tuning and alignment tuning principles that involve things such as, toe in/out front/rear to shift the pivot point of a car further rearward. In addition, I am trying to more fully understand weight transfer on individual wheels.....how this affects the way the car handles, and how I can utilize this and optimally set-up the Miata for the track.

Lateral acceleration.

So what's your question? I explained why it does what it does in my original post and the circumstances haven't changed. You can call it a drift or a donut or a turkey pot pie if you want, the fact of the matter is that you're still just going in circles.

Bushflyr, I appreciate your explanations. You clearly know much more about physics than me.

The reason I ask so many questions about the subject, is that I was trying to figure out if there was a point, front to rear where the lateral acceleration could prove an exception to the rule that objects in a car throw left in a right hand turn. Futhermore I was investigating if I could "cheat" the rule by initiating a drift, which alters the ratio of front/rear acceleration, pivot point, etc.

I think it would be really great if you come out to the next auto-x. We'll do fun runs together.

You can give me a physics lesson, and I'll show you how to quickly navigate a race track

Afterward, dinner is on me. How does turkey pot pie sound?

This is a lot simpler than some are making it. Inertia. A body (read Mass) at rest will tend to remain at rest until acted upon by another force. A body in motion will tend to remain in motion until acted upon by another force.

If you are driving at 20 mph and hit the brakes, your "body" will tend to remain moving forward at 20 mph, until acted upon by another force. The other force could be your seatbelt, to prevent you from breaking your windshield, or it could be the windshield, to prevent you from exiting the vehicle.

If you are driving at 20 mph and turn right, your "body" will tend to remain in motion (go left) until acted upon by another force. Again, the other force could be your seatbelt, or your side pillar or window.

It makes no difference if you're drifting, doing doughnuts or going in a straight line. Bodies at rest remain at rest until acted upon by another force. Bodies in motion remain in motion until acted upon by another force.

When I saw "physics" I thought this was going to be string theory or something very complicated.

Can entropy be reversed?
