feedback while driving

so while driving to school, instead of thinking about the road and how sleepy i was, i did something worse.

i thought about cog sci!

feedback in particular

so when steering, people either steer with

1. one hand or
   
2. two hands

obvious enough. when steering with one hand, you put your hand not directly parallel to your body but slightly across to get that leverage (think gangster-driving with the seat back...)

and when you steer with 2 hands you are usually in the 10'n'2 position or a variance of that

now for feedback:

first off the goal of steering is either to turn or more likely (even though its an automatic, innate response) keep the car in the center of the lane

while steering with 1 hand, its very easy to turn, usually a little too easy. and what ends up happening is a form of positive feedback since if you let your hand move naturally to where it wants to go, it continues in that direction. the overall effect of this is an uncontrollable, extreme turn. (if unchecked, the turn will turn into a circle)

while steering with 2 hands, one can exhibit negative feedback much more easily. since each hand naturally wants to go one direction, the overall personal utility (in terms of personal convenience) favors going forward with quick response times from straying too far from the center of the road.

just to note, negative feedback is the favoring of staying in the center so all the straying to one side or the other ultimately results in a preference toward the center

ok i'm done
