I hope that if they do drag racing, they do a cross between gt5 @ Indy & forza 4.
Imagine this, you go online and enter the S.S.R.X
Drag lobby , pick your car and enter the course;
You pull out of the garage and into a large parking lot in the middle of SSRX. Here you can cruise around and ogle each others rides, after you sniff butts and decide to throw it down,
You pull up to one of the sets of drag lanes and lock in where a tree counts you down and off you go. At the end of the strip there are return lanes on either side the go back the the parking lot.
The lanes could be organized by length 1/4, 1/2, 1 mile and full SSRX length. The inside of SSRX would provide ample width for multiple lanes of each length.
Just my idea, there's lots of refinements to be had but that's my two cents
