I suppose that could be possible as a special event, like certain endurance races they host throughout the year.
I'm glad to see they are doing this, the currently deployed Time Attack had a very low turnout because there was little incentive to join an empty track. Most people seemed to prefer doing a practice session to work on passig zones and navigating traffic. It will be interesting to see how long it takes the community to adopt the time attack, or how quickly the interest fades.
