Thank you very much for the advice
One of the questions I was going to ask is if the draw fly feature would be practical/useful for this purpose so you answered that for me, thanks!!
In my opinion to draw/fly function works best when the drone is higher off the ground so that the line that is drawn is clear in terms of its geographical GPS positioning.
For your application I would use the TapFly ‘forward’ function. I would set the throttle response functions to their minimum so that you don’t over control the drone. The TapFly function will maintain altitude. You can then use the left throttle to adjust the course as needed (in a moderate way) as you go down the road. As before practice this in an open field first.
