Field notes from practice, and upcoming appearances by Johann Tay.
Two streams of content are published here. The Travelog covers observations from practice — crash investigation insights, emerging technology assessments, professional commentary, and field notes that don’t fit neatly into a journal paper but are worth putting on record. Events list upcoming appearances, CPD sessions, and conference presentations.

Observations from practice — crash investigation, vehicle technology, road safety, and the road transport system.
I have spent a good part of the past week thinking about driver perception, prompted partly by some thoughtful comments in Linkedin on my last post. One theme kept returning: people use “saw” to mean two different things, and in a collision case the difference decides who is at fault. Did the driver see the…
I have driven for decades. I can do it without thinking, which is the point: the skill has long since dropped below conscious effort. Then I started teaching my eldest, and discovered I could not explain it fast enough to be useful. That gap surprised me. The problem was not that I lacked the knowledge….

My thanks to SAE-A for the invitation, to the members who gave up an hour of their afternoon, and to my co-presenter…
This morning I watched Mike Nelson’s interview with Matt Moore, who leads the Highway Loss Data Institute (HLDI) in the United States. The subject was a major new study HLDI published in December 2025 examining the real-world effectiveness of Mazda’s advanced driver assistance systems across model years 2015 to 2023. I found several findings to…

The geometry is compressed, sightlines are constrained, the signs are prominent, and the driver arrives with their attention already raised. These locations are difficult to get right, but they are at least legible as problems. Other intersections are dangerous for the opposite reason. The approach is open,…
Threshold treatments and continuous footpath designs are appearing in increasing numbers across Victorian local government areas. The intent is legible from the streetscape: by raising the pavement at a driveway crossing or minor road entry to match the footpath level, and by carrying footpath materials and markings across the junction, the design signals to drivers…
