An exploit came to our notice last night, one that we've not seen before. Although I've noticed that you can 'pit' when leaving the garage when joining midrace.
W17, 'Mustpit' enabled
What they do is pretend to accidently false start, telepit, which nullifys their penalty, leave the garage, drive into a pit space do their pitstop (no damage of course) and carry on. This all takes just a few seconds and the rest of the field have only gone a little way and of course they still have to pit. Keep an eye out for people that false start and telepit immediately.
Hope that makes sense.
