“…Mindfulness, understood as a trait, is the natural mindful tendency of each individual ( Brown and Ryan, 2003 ) and has been negatively related to risky driving ( Feldman et al, 2011 ; Panek et al, 2015 ; Koppel et al, 2018 ; Murphy and Matvienko-Sikar, 2019 ). In a review of effective interventions for reducing driving anger, Deffenbacher (2016) concluded that MBI reduced anger and facilitated more adaptive expression of anger in drivers ( Diebold, 2003 ; Kazemeini et al, 2013 ). Some studies have also found that MBIs improve performance on driving simulators, although methodological limitations, such as a very low number of participants and the lack of baseline measurements as in Kass et al (2011) , or the application of only a 10 min mindfulness meditation as in Reynaud and Navarro (2019) , and the scarcity of research in this field mean that no firm conclusions can yet be drawn on this issue (for a review, see Koppel et al, 2019 ).…”
