To varying degrees each of these technologies has been driven by criteria pollutant regulations. Because of this, viewing the deployment of such features in the broader context of safety regulation-driven and optional features serves to better characterize deployment of technology in the automotive fleet. 1.3 Research Objectives Thisthesis serves to address the following primary research questions described below. Mass Impact What has been the impact of safety and emissions requirements and 19
