When it's hard to tell, you don't need to mow yet.
I end up missing a strip, or mowing a half width and doubling the time.

Modify the wheels to be steerable. Put stepper motors on them, with
bluetooth. Build an iPad or android app to control the stepper motors
for steering, using GPS. Put Velcro on the mowers and the iPad/android
controller.
Seriously, I haven't experimented, but I've thought about it.
What I think would work is to buy one of those "laser levels"
that makes a red line appear on a wall.
Put velcro hooks on it, and the pads on the side of each mower.
Stick the box on the side of the mower so that the line is on the ground
in front of you.
When you start each row, find or place an object to aim at after you
turn around at the far end.
Solution two: self-propelled mower. Divide the blade length by
3.1415926535... Find a piece of pipe as close to that diameter as
possible and plant it firmly into the center of the yard. Get a length
of rope that will reach from the pipe to the closest edge of the yard.
Fasten one end to the pipe and wrap all the rest of it around the pipe.
Place the mower next to it and fasten the other end to it. Start the
mower and let it go. It will circle the pipe, unwinding the rope.
Since the circumference of the pipe is slightly less than the blade
with, each circle will overlap the previous one by a hair. When it gets
to the end of its rope, untie it and do the corners of the yard.
Solution three: Buy a fence and a sheep.
