The front passenger seat generally refers to the position next to the driver. In China, the driver's seat is on the left side, so the front passenger seat is on the right. However, not all countries in the world have the driver's seat on the left side; some have it on the right, such as Japan, the UK, Australia, Hong Kong (China), Turkey, and South Korea. Therefore, in these countries or regions (e.g., Hong Kong), the front passenger seat is on the left. Below are the roles of the front passenger seat: 1. Navigation: While driving, the driver cannot consult a map, so this task can be handled by the front passenger. Sometimes, navigation devices may also make mistakes, and the passenger's role in navigation becomes crucial. 2. Observing road conditions: The driver cannot look around while driving to find the destination, but the front passenger can, providing information such as the current route and address numbers. 3. Helping the driver alleviate physical and mental fatigue: During long drives, especially on highways lasting several hours, if the front passenger falls asleep immediately, it can accelerate the driver's fatigue. Conversely, maintaining conversation with the driver can help slow down the rate of fatigue.

I've been driving for many years, and the front passenger seat is always on the right in left-hand drive countries like China or the US. This design makes it more convenient for the driver to operate, avoiding interference with the view or accidental contact with controls. If the positions were reversed, like in right-hand drive UK where it's on the left, safety considerations still take top priority overall. The airbag is specifically designed for the right side to protect passengers in case of an accident. I recommend keeping the front passenger seat tidy and free of clutter, as objects can make airbag deployment more dangerous. The position also affects daily convenience: it's safer and more straightforward to open the door on the right when parking by the roadside. Understanding this can save a lot of hassle.

In daily car use, I noticed the passenger seat is always on the right in left-hand drive vehicles, which is most convenient. For example, grabbing coffee or picking up packages allows quick exit without walking around the car. But when traveling to right-hand drive countries like Japan, the passenger seat being on the left feels awkward at first and increases scrape risks. This position change stems from traffic rules: passenger seats align with driving side (right-side traffic = right passenger seat). I also observe this design minimizes driver distraction. It's wise to remind beginners or friends borrowing cars about this positional difference to prevent mistakes.

Traveling around the world, one often notices the different positions of the front passenger seat. In most countries like the USA, it's on the right; however, in the UK and Australia, it's on the left, a tradition originating from the customs of the horse-drawn carriage era. This affects the interior layout design of vehicles, and driving a right-hand drive car requires a few days of adaptation to avoid opening the wrong door. The seating position is crucial for safety: the correct seat arrangement protects passengers in accidents. For international self-drive tours, it's advisable to check the rental car instructions in advance to familiarize oneself with the setup.
