A quiet morning at ''Vancouver''. Suddenly, a loud crash: two cars collide. No one is badly hurt, but both drivers blame each other You decide to talk to ''three witnesses''. [[Talk to the woman witness->Woman]] [[Talk to the man witness->Man]] A young woman stands near the crosswalk. “I saw it clearly,” . You may ask question. [[What did you notice first?->Woman: Sequence]] [[What about the traffic light?->Woman: Light color]]He is a delivery worker. “I was unloading by the café when it happened.” Choose one: [[Which car moved first?->Man: Light Order]] [[Was anything blocking your view?->Man: Sequence]]A schoolboy sits on the curbside, and has a backpack. “I was waiting for the bus,” he says. Ask one: [[Where were you looking?->Child: Direction]] [[Did you see the light?->Child: Light]]“I heard a horn, then saw the //''blue car''// turning left too quickly,” she says, then : “Or... maybe the //''red one''// was already fast?” [[Continue to What about the traffic light?->Woman: Light color]] [[Continue to the next witness Man->Man]] [[Continue to the next witness Child->Child]] “I could see both cars. The pedestrian signal was ''green'' for me, so cars must have had ''red''.” She unsure. “Unless it just turned.” [[Continue to What about the traffic light?->Woman: Sequence]] [[Continue to the next witness Man->Man]] [[Continue to the next witness Child->Child]]“Honestly, a delivery truck blocked part of my view. The light maybe was ''green''... I think .... at least a second before the crash,” he says, uncertain. [[Continue to What about the sequence?->Man: Sequence]] [[Continue to the next witness Woman->Woman]] [[Continue to the next witness Child->Child]]“I saw the ''red car'' enter first — maybe too early,” he says. “The ''blue'' came fast from the other side.” [[Continue to What about the traffic light?->Man: Light Order]] [[Continue to the next witness Woman->Woman]] [[Continue to the next witness Child->Child]]He points across. “I faced the ice cream shop. I saw them from the side. It was scary.” [[Did you see the light?->Child: Light]] [[Think it through->Reflection]]“The light was ''yellow''! My teacher says ''yellow'' means slow down, not speed up,” he says proudly. [[Where were you looking?->Child: Direction]] [[Think it through->Reflection]]Now, you have three perspectives: • Woman trusts the pedestrian signal timing. • Man saw the red car move first (but had a blocked view). • Child reported a yellow light. What do you think really happened? ........ You can return to the start to review the scenario: [[Restart the investigation->Start]] Or pick one of the three endings below for the story: [[Conclude the red car is at fault->Ending: Red Fault]] [[Conclude the blue car is at fault->Ending: Blue Fault]] [[Conclude they share blame->Ending: Shared Fault]] You conclude the ''red car'' entered the intersection too early on'' yellow'' light, creating the conflict. What do you think. Let’s review the scenario again. [[Restart the investigation->Start]]You conclude the ''blue car'' accelerated into the intersection on ''yellow'' light, failing to yield to a turning vehicle. What do you think. Let’s review the scenario again. [[Restart the investigation->Start]]You conclude both drivers misjudged the ''yellow'': one entered early, the other accelerated. The report recommends shared responsibility. What do you think. Let’s review the scenario again. [[Restart the investigation->Start]]
