“…Freedom of exterior camera placement is an opportunity for optimizing CMS, but also entails risks. In other contexts, vertical perspective change has been shown to affect distance and time-to-contact estimation (Daum & Hecht, 2009;Hecht et al, 2015;Leyrer et al, 2015;Ooi et al, 2001;Steward et al, 1993). Effects on distance estimation also generalize to CMS (Bernhard & Hecht, 2020).…”
