Size

The size of the packet is always 20 bytes.

Type

The packet type from the ISP_ enumeration, always ISP_CSC.

ReqI

ReqI is always equal to zero.

PLID

The player's unique ID.

CSCAction

A value from the CSC_ enumeration:

• CSC_STOP: The car stopped moving.
• CSC_START: The car started moving.

Time

The timestamp of the state change.

C

A CarContOBJ containing details about the car.

Notes

Starting and stopping have some tolerance of around 1 or 2 km/h, therefore slowly crawling from a standstill will not be detected as "starting", and not staying on the brakes may be detected as "stopping" even if the car never actually completed stopped. If you need more precision, you should probably use IS_MCI packets instead, while allowing enough tolerance that just turning the steering wheel doesn't register as "moving".
