There is nothing bad about putting psychedelic trance in racing games, or any game for that matter. I find that people who would usually be close-minded to certain music can start to like certain things if it goes along as a soundtrack to a movie or game. And I am always open to the risk of introducing people into the genre.
I know I drive around in my car with psytrance, goa, chill, industrial, and dark-electro playing almost all the time, even when I am going measurably fast and competitive on the highway.
If I remember listening to samples of GT4 Kicks with all the Psytrance artists on it, the music wasn't the best, it sounded kinda' cheesy with the racing, engine, and autoshop machinery sounds they put into the tracks as part of the music, but it was still listenable and respective of each artist's sound.
Honestly, I think some Shpongle would go well with a dish washing liquid commercial.
Did anyone ever play the original Vectorman on Sega Genesis. Well, the soundtrack for the game was influenced by various electronic club, rave, festival, etc. music of the early-to-mid 90s, and if I were older, I would have probably looked more into electronic music sooner. I especially liked this track(not a perfect rendition of the original track), which I find it hard not to hear goa-influenced elements in . A track like that can slowly bring people who research a type of track they heard in a videogame, and in today's more music-accessable age, I am sure anyone interested can eventually find what they are looking for.
