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.
