I don't want to give others the smartest reasons

The smartest reason for not wanting to take someone is based on maintaining personal psychological boundaries and avoiding potential interpersonal risks. Directly expressing genuine needs or proposing alternative solutions is often more effective than making perfunctory excuses. Refusing colleagues to hitchhike in the workplace can emphasize travel conflicts or privacy needs, such as taking detours to pick up family members or handling personal affairs. Clearly state that the schedule is fully occupied, while maintaining politeness and avoiding being misunderstood as deliberately distant. If the other party insists on the request, it can be suggested to use public transportation or carpooling software to transfer responsibility to a third-party platform.

Refusing friends to ride in social situations can indirectly mention the condition of the vehicle or insurance restrictions, such as recent insufficient maintenance or policy clauses that exempt non family passengers from liability. This type of objective reason is less likely to trigger emotional resistance and implies the issue of risk sharing. For frequent requesters, a unified response script can be developed in advance, such as getting used to conducting phone conferences in the car or needing alone time to recharge.

Long term maintenance of the rationality of rejection requires attention to attitude consistency and compensatory behavior. Occasionally providing other assistance such as calling a taxi or sharing real-time traffic information can balance interpersonal relationships. Establishing clear ride rules such as advance booking or fuel sharing principles can reduce passive requests from the source. Psychologically accepting moderate rejection is a necessary ability for healthy socialization, while excessive catering may lead to the accumulation of implicit reservations.
