The data pointed at one tension: cyclists are distracted exactly where they need awareness, and the tools meant to help either ignore safety or pile on more to read. Four questions framed the design, each tied back to a finding.
turned each finding into a question to design against →increase rear awareness without increasing rider anxiety?
reduce phone dependence while keeping navigation confidence?
warn riders before infrastructure turns dangerous, not during the danger?
make ride information readable in under a second?
