Note: This procedure requires editing a game file; creating a backup copy of the file before proceeding is recommended. With a text editor, edit the "kitt_data" file in the "\davilex\knight rider\data\vehicle" folder. Edit the value of "DirectionRatio" line under the "TURBO BOOST" heading. The default value is "55". Changing it to "65" should enable you to jump most walls or obstacles without having to use the crates. Changing it to "70" to "75" will get you to the rooftops without a problem.
