It is because fresh, better, new or updated content doesn't make the old one ship ( change the last p letter to something else lol )
Also, old westhill is unique, where there are turns left and right and you can drive full speed. I do not understand what is so boring to drive full speed and why all the times brake pedal is needed, especially when full speed is granted, approved and badly needed.
So yeah, reason why I would like to keep old westhill track is it is fast and turns left and right with full throttle and still having a nice racing! Not much brake pedal needed
So, good bye old westhill, I am going to miss you, but at least you get a superb enhancing to the layout. LET'S APPLAUSE! *clap clap clap clap clap clap*
