So what you mean is:
If someone clicks on a car to edit, a txt file is written (maybe called the carID.txt). Then if someone else clicks on that car to edit it, it says that it is already being edited by someone else because the txt file exists? So what happens if that person who clicked first closes his browser before updating the car? How can that text file be automatically erased?
I think I'll just assume that this wont be a problem, and if someone overwrites someone elses edit then too bad.. :-)
