    uint8         m_carIdx;                   // Index of the car this lap data relates to
    uint8         m_numLaps;                  // Num laps in the data (including current partial lap)
    uint8         m_numTyreStints;            // Number of tyre stints in the data

    uint8         m_bestLapTimeLapNum;        // Lap the best lap time was achieved on

    uint8         m_bestSector3LapNum;        // Lap the best Sector 3 time was achieved on

    LapHistoryData          m_lapHistoryData[100];	// 100 laps of data max

{
    uint8     m_endLap;                // Lap the tyre usage ends on (255 of current tyre)
    uint8     m_tyreActualCompound;    // Actual tyres used by this driver

    uint16    m_sector1TimeInMS;       // Sector 1 time in milliseconds

    uint8     m_lapValidBitFlags;      // 0x01 bit set-lap valid,      0x02 bit set-sector 1 valid
                                       // 0x04 bit set-sector 2 valid, 0x08 bit set-sector 3 valid
};

Additional info:
This packet contains lap times and tyre usage for the session. This packet works slightly differently to other packets. To reduce CPU and bandwidth, each packet relates to a specific vehicle and is sent every 1/20 s, and the vehicle being sent is cycled through. Therefore in a 20 car race you should receive an update for each vehicle at least once per second.

Note that at the end of the race, after the final classification packet has been sent, a final bulk update of all the session histories for the vehicles in that session will be sent.
