Chris thanks for the questions.

first one. if you crash and end up on a different part of the track or by mistake a marshall places you there then you will do the following, (1). attempt to rejoin the track where you left. this is not always possible depending on track markings, impeding other cars on the rejoin etc. So if you cannot do (1) then (2) wait keeping clear of the racing line, allow all the cars that were in front of you to pass and then impose a delay on yourself to account for your crash, then carry on. if i as the referee see the incident and have time i will call the wait and tell you to go, should you go earlier than i think then i will give you a "stop go penalty" to account for any advantage i believe you have made.

the common problems i have seen is the racer realises that he will lose more time by rejoining than if he waits, however if I believe that it is possible to rejoin where leaving then again a penalty will be issued to account for that "gain".
another issue is that if he was two car lengths behind a car then he should rejoin the same distance behind it. however in reality had he crashed and not left the track he would have restarted considerably further back than two car lengths, which is where the self imposed delay comes.

another issue, you are hit by another car causing you to crash, so you rejoin but do not wait because you believe the crash was not your fault and so you attempt to carry on in the same position. however it doesn't matter how the crash was caused, you take the delay or risk the penalty. i might not have seen the original incident but see you driving off so you get a penalty, i may well have seen the original incident which caused your crash and i might be lenient in how much time i give you to restart, as long as you make an attempt to impose a delay then i might let you go.
