Does the RSA ask why drivers think it is okay, whether they thought it was okay two years ago and whether this position has changed? The immediate question that comes to mind is whether drinking at home has changed this. Has the RSA tried to get to the bottom of this? Are there further indications of where the RSA thinks it would go with this information?
