Design Evolution - User Inquiry
Interviewed 3 participants:• Max - Drives regularly from Eugene to
Seattle. Has offered rides in the past. Main motivation is splitting fuel cost
• Traci - Doesn’t own a car; would be interested in finding rideshares
• Joe - Primarily a driver & would offer rides. Also interested in finding rideshares.
