If I know your exact state of mind, I will be able to predict your car’s trajectory by modeling your current state of mind
This is tangential to the direction of the post, but in fact you will not be able to predict the car’s trajectory from the driver’s current state of mind, since it depends not only on that state of mind, but also on everything that might happen on the way. Maybe a road is blocked and the driver goes another way. Maybe the driver has a crash and must abandon the journey. You will certainly not be able to predict the detailed movements the driver makes with the car’s controls, since those will depend even on transient gusts of wind. Purposes are not achieved merely by making a plan, and then executing it.
