I've always asked me what does this parenthesis mean. Is it taken from anywhere?

maybe he just called it that because it's a song made for driving in the 'fastlane'
idk speculation but it could be liam's representation of what driving fast feels like. i mean the samples that are used are cars going pretty fast....?

nice interpretation!

It still doesn't explain it. The tv series is from 2003 and speedway has been in done in 1994. So they are probably two different things.

Probably doesnt refer to anything just a random title
