From the TCR Preview:
"This year the TCR competitors will use the circuit’s older layout that includes the smoother “esses” at the end of the pit straight instead of the sharper left-hander. This is to limit the risk of a pile up at the start and to favour overtaking manoeuvres"
I don't think it favours overtaking or prevents a pile up. They should redesign T1 or use last year's layout. TCR Germany got 41 cars through there, twice.
