Note: This procedure involves editing a game file; create
a backup copy of the file before proceeding.
Enter the "vehicles" sub-directory that is inside the
game directory. Use a utility such as WinZip or PKUnzip
to extract the "physics.txt" file from any of the .zip
files. Use a text editor to edit the "physics.txt" file
and change the "//idealMaxSpeed" entry to "200".
Save the file and add it back to the original .zip file.
The top speed bar will be full for the vehicle when the
game is played.
