Since its late, and im not very good at problem solving, i cant figure out the answer to this simple little problem.

I have a car that i want to move in the direction it is pointing. I assume that i would use the formula (in many posts on this site) for moving towards a point in order to move it, the only problem is that the point can be anywhere the car is facing (360 degrees i suppose). I doubt that it matters how far away the point is either, as the car will just drive as long as you hold down a key. how do i find this point...?
