I have successfully built an EV3 Race Car with instructions from a fan-made book made by Laurens Valk. In the book, he tells how to make my blocks for the rack-and-pinion steering and how to make a remote-control program with those custom blocks, too. I am eager to try it out, but unfortunately one of the my blocks that are required does simply nothing. To be more specific, it does 100% nothing. In fact, it doesn't even show that screen you see when you run the program.
This is the center my block, and according to the book it's supposed to check to see if the front wheels are not perfectly straight like the rear wheels (which aren't even supposed to turn, anyway) and if so it will realign them so that they are aligned and it should lock them in place. Here is the given blueprint from the book:
The author is no longer active on the website where you can contact him, and yes, I did update the EV3's firmware and reinstalled the software.
I don't see any reason for the program to not work, so I'm hoping one of you will help to fix it.
Oh, and you'll probably want to know about the other necessary details so here's the part of the book that involves this car: https://magbuhatrobotics.files.wordpress.com/2017/05/chapter-12.pdf
