-- Whole thing is still at very early stage of development, a lot might and possibly
-- will change. Currently whole thing is limited to sort of original drifting mode
-- level. Observe things that happen, draw some extra UI, score user,
-- decide when session ends.
-- This mode in particular is meant for Track Day with AI Flood on large tracks. Set
-- AIs to draw some slow cars, get yourself that Red Bull monstrousity and try to
-- score some points.
-- Key points for future:
-- • Integration with CM’s Quick Drive section, with settings and everything;
-- • These modes might need to be able to force certain CSP parameters — here, for example,
-- it should be AI flood parameters;
-- • To ensure competitiveness, they might also need to collect some data, verify integrity
-- and possibly record short replays?
-- • Remote future: control scene, AIs, spawn extra geometry and so on.
