It's Hard to Drive Straight

It's hard to drive straight and accurately.

 These tracks down the centerline (yellow) show the difficulty a new driver had in:

1. finding the centerline
2. driving straight. 

And she was trying *really* hard to do it right.

The white arrows indicate the widest tracks in her attempts. If you look carefully you can see she was able to generally hone in on X but getting there and leaving there were harder.

This represents about 4 attempts at Training level 1 and 4 at Training Level 2. We'd expect this to improve with more practice BUT......

I have noticed in this ring after 2 weeks of drivers practicing and trying HARD to drive straight, there is a pretty wide variation down this centerline.

A judge sitting at C has an easy job of assessing accuracy: if a 10 is perfectly straight, then anything less than perfectly straight has to be something less than 10. 

So, how is it that this man can 'drive' so straight? Would he get a 10? 

Practice, practice, practice!
