Lyft product design: a pooled ride where passengers heading the same way share a car

Lyft wants a carpool option in which riders heading in similar directions share one car. Design that shared experience. Walk through the goal you would set, which riders and drivers you would design for, the problems of sharing a car that you would solve first, what you would build and how you would measure success. ```hint What sharing costs the rider Ask what a rider gives up by sharing a car instead of riding alone, and what would make that sacrifice feel worth it. That points to the problems worth solving first. ``` ### Clarifying Questions - Is this a new option for Lyft, or a redesign of a shared-ride product it has offered before? - Does "carpool" mean Lyft matching riders who do not know each other, people who already know each other riding together (such as coworkers), or both? - What is the main goal: more riders through lower prices, more trips per driver hour, fewer cars on the road, or a mix? - Are drivers in scope, or only the rider experience? ### What a Strong Answer Covers - A goal that ties the carpool product to Lyft's business, and a deliberate choice about who shares the car - Both sides of the marketplace mapped, riders by trip type plus drivers, with a justified focus segment - Pain points specific to sharing, such as detours and unpredictable arrival times, riders added mid-trip, comfort and safety with strangers, and the price gap versus a private ride - Prioritized solutions with explicit trade-offs between matching efficiency and the rider's experience - Success metrics such as match rate, detour time and repeat use, with safety, cancellation and driver-earnings guardrails ### Follow-up Questions - Shared rides only work when enough riders are going the same way at the same time. How would you handle a new city or quiet hours? - If showing co-riders' profiles makes riders more comfortable but leads some to cancel because of whom they were matched with, what would you do? - How would you set the discount for a shared ride so that riders choose it without hurting driver pay or Lyft's margins?
