作者：

Highlights：

• This study proposes the use of linguistic politeness in vehicle speech interfaces.

• Drivers evaluate polite vehicles as more trustworthy, and perceive the vehicle's instructions as more acceptable.

• Providing reasons for requests and expressing gratitude for drivers' cooperation can be an optimal instruction strategy.

• This study identifies the layers of heuristics in the process of shaping trust in autonomous vehicles.
