The May planner initially selects a trajectory it believes will safely complete the turn.

At that point, the planner shifts focus from avoiding the curb entirely to minimizing the severity of a potential curb strike. To reduce speed before the expected contact, the Ego brakes at €“3.5 m/s²). Because the trailing vehicle is following so closely, this deceleration makes a rear-end collision likely. The Ego predicts a potential rear-end collision and elects to reduce brake force to lessen the impact severity. Moments later, the trailing vehicle strikes the rear driver-side bumper of the Ego and then drives away. Future improvements are underway to give the planner a policy option to steer away from curbs. This new capability will help the vehicle avoid situations where braking becomes the only remaining way to manage close curb proximity.","occurredAt":"2025-12-01T12:00:00.000Z","reviewStatus":"reviewed","modelId":null,"deploymentId":null,"companyId":"8f52c3ed-fb8c-4f25-8c75-c7c9f912776d","aliases":[],"collisionRisk":"none","reviewNote":null,"severity":"minor","rootCauseCategory":null,"rootCauseDetail":null,"affectedUnitsCount":null,"affectedUnitsBasis":null,"remediationStatus":null,"regulatoryAction":null,"regulatoryBody":null,"propertyDamageEstimateUsd":null,"damageEstimateBasis":null,"bodilyInjurySeverity":"unknown","fatalityCount":null,"lossCostClass":null,"sourceQualityTier":null,"oshaRecordable":null,"oshaCaseNumber":null,"rootCauseDisclosed":null,"publicDisclosureDate":null,"insuranceClaimPublic":null,"createdAt":"2026-07-12T05:01:44.490Z","updatedAt":"2026-07-14T21:53:38.800Z","model":null,"deployment":null,"company":{"id":"8f52c3ed-fb8c-4f25-8c75-c7c9f912776d","name":"May Mobility","slug":"may-mobility","description":"May Mobility is an autonomous-shuttle / microtransit company running driverless public AV services (autonomous Toyota Sienna minivans).
