Put on top of the script:

Code:

new InVehicleTime[MAX_PLAYERS];

Then put under OnGameModeInIt:

Code:

SetTimer("InVehicleCheck", 1000, true);

Then make a public:

Code:

forward InVehicleCheck();
public InVehicleCheck()
{
     for(new i; i < MAX_PLAYERS; i++)
     {
        if(IsPlayerInAnyVehicle(i))
        {
          new Float:Velocity[3], output[80];
	  GetVehicleVelocity(GetPlayerVehicleID(playerid), Velocity[0], Velocity[1], Velocity[2]);
          if(Velocity[0] == 0 && Velocity[1] == 0 && Velocity[2] == 0)
          {
             if(InVehicleTime[playerid] < 10)
             {
                 InVehicleTime[playerid] = InVehicleTime[playerid]+1;
             }
             else
             {
                 SendClientMessage(playerid, -1, "You are not moving with your vehicle for 10+ seconds!");
             }
          }
        }
     }
}
