Ralph, Johnson-Rodriguez Research ASE Perceptions
We found that many respondents did not believe that speeding was particularly dangerous, and that people with these beliefs were less likely to support automated speed enforcement. However, providing a message about the dangers of speeding was effective in increasing support for automated enforcement, especially among people who did not hold extreme beliefs about the (lack of) danger of speed.
