It's because I find it to be totally underwhelming and lacking the charms and wonder of its predecessor; World of Motion. WoM was a fun and wacky trip through the history of transportation and left riders inspired, just like the rest of the old EPCOT Center, and left them excited for what the future of transportation will hold. Test Track is cold and lifeless and a massive advertisement for General Motors, and leaves me feeling no form of inspiration whatsoever. It's essentially a fast ride through a black building with little theming and a finale that can easily be replicated with one's own car. For me, it just leaves me feeling nothing. That's why.
