| Abstract: | We comment on the analysis of the critical behavior of a layered driven diffusive system recently done by Achahbar and Marro. We discuss why we believe their method of taking the thermodynamic limit and determining the order-parameter exponent  leads to unreliable estimates. |
| Keywords: | Driven diffusive systems critical behavior finite-size scaling computer simulations |
