distorted input image in draw_lane

Hi,
The input image is not undistorted before the calculated lane is added to it. It can be problem if the lane is not in the center.
Thanks for your code. It is very good to learn.

This reply comes super-late, but you're right, thanks for pointing that out! I'll change it so that the image is being undistorted first.
