Racecraft: overtaking without collecting penalties

The system does not decide who was at fault, it charges everybody involved, and that single design decision should change how you overtake. Being right is not a defence when the points land on your account anyway.

What the rulebook charges

The official sporting code publishes the values directly. On pavement, light contact with another driver counts 0x, wheels off the racing surface 1x, loss of control 2x, contact with another object 2x and heavy contact with another driver 4x. On dirt the table is the same except that heavy contact counts 2x rather than 4x.

Two rules make those numbers sharper. Where several incidents happen at once, only the most serious is counted, so a 2x that causes a 4x is charged as 4x. And the software does not attempt to determine fault, because as the code states it would not be possible, so incidents are assessed to everybody involved.

The limit is the part people discover the hard way. Series typically carry an incident limit that automatically disqualifies and removes a driver on reaching it, and the code gives 17 as an example figure. Four heavy contacts is 16 points, and the fifth ends the race regardless of who caused them.

Where the sessions weigh differently

The code publishes weights for how a session averages into a safety rating: Time Trial 0.35, lone practice 0.35, open practice 0.50, lone qualifying 0.35, open qualifying 0.50, warm up 0.50, heat 1.00 and race 1.00. All other session types carry 0.00.

That table has a practical reading. An incident in open practice costs half of what the same incident costs in a race, which makes practice the correct place to try a move you are unsure about. Trying it for the first time in a race costs double and takes somebody else's evening with it.

And the counting does not stop at the flag. Incidents are counted throughout the session including the cool down period after the chequered flag, which ends only when all participants have crossed the line or left. The celebration lap is still a scored lap.

Where the responsibility sits

For lapping, the code is explicit: in all cases it is the responsibility of the faster car to safely overtake the slower car, and the responsibility of the slower car to maintain a consistent line. A slower car being lapped is strongly recommended to make every reasonable effort to facilitate a safe pass.

That wording is worth reading twice, because it splits the duty rather than assigning blame. The faster car owes the safety of the manoeuvre; the slower car owes predictability, not evasion. A slower driver who dives out of the way unpredictably is failing their half of it.

Oval racing has its own hard rule. Drivers shall not pass cars in their own pacing line on the left before the start finish line, and attempting to improve position that way draws a black flag stop and go from race control. That is a penalty rather than an incident, and it is not negotiable.

The three moves that pay

The first is the pass you set up a lap early. Following closely through the two corners before the braking zone costs you nothing and gives you the exit speed that makes the move a formality. Attempting it cold costs a 4x when it goes wrong.

The second is the pass you do not make. If a move requires the other driver to cooperate, it is not a move, it is a hope, and the arithmetic of 4x for heavy contact against one position makes the maths obvious over a season.

The third is the clean rejoin. Wheels off the racing surface is 1x and loss of control is 2x, so a driver who runs wide and rejoins carefully pays one point where a driver who snaps back onto the racing line pays two and often takes somebody with them.

Frequently asked questions

Do I get incident points even when it was not my fault?

Yes. The code states the software does not attempt to determine fault, so incidents are assessed to everybody involved.

How many heavy contacts end a race?

With an example limit of 17, four heavy contacts at 4x is 16 points and the fifth incident of any kind ends the race.

Whose responsibility is a lapping pass?

The faster car owes the safety of the overtake and the slower car owes a consistent line. Both halves are named in the code.

Do incidents after the chequered flag count?

Yes. Counting continues through the cool down period until all participants have crossed the line or left the session.
