Basic line geomeotry. It is not hard to tell when a road is pointed
directly at you.

It should work perfectly--provided that two convenient roads or other lines
happen to intersect at exactly the position you are overflying.

Or you are in control of the airplane and make it go exactly over
the road intersection.
