Title text: As far as treachery-as-driving-music goes, Katamari music is matched only by Guitar Hero music.
The best way of explaining this comic is to explain the game Katamari Damacy, which music is also referenced in frame 3. In the game, the player has to "cling" his initial object to smaller objects in the playfield in order to get larger as a whole. As clinging smaller objects progresses, the larger objects initially ignoring the central player object will cling to it (thus adding more points and progressing through the levels).
In the comic, Cueball is remembering this strategy by playing the game a lot, and drives his car into a mailbox, which he states "it looked smaller than me".
The image text states that trusting your car to a person that is playing Katamari will surpass the chance of losing it to someone that is playing Guitar Hero. The latter will probably will rock your car to death while playing songs. An alternate explanation is that the road one is driving on might appear as the "note highway" of Guitar Hero; in this case, the driver would weave rapidly between lanes in order to "hit all the notes," which could prove far more devastating than simply rocking one's car.
