I made a total of three car reservations: one at Auckland Airport and two at Christchurch Airport. The latter were driven by Mr. Ma and myself as the primary drivers. The car driven by Mr. Ma seemed to be in better condition and was noticeably more fuel-efficient for the same trip. Other driving experiences with that car were also very satisfying. Since this was our first self-driving trip abroad, and we were a group of retirees traveling together, there were numerous concerns. For example: worries about having too much luggage and insufficient trunk space; being unfamiliar with right-hand drive and left-side traffic rules; older drivers with slower reaction times needing to take turns driving; multiple phones and navigation devices needing charging; and whether the phone holder would be convenient to use. Thankfully, all these concerns were addressed without any issues, ensuring the safety and smoothness of the trip. This was highly appreciated by all of us. Moreover, the process of picking up and returning the car was swift and simple, which was especially helpful for catching flights after returning the car. Moving forward, whether traveling domestically or abroad, renting a car will always be our top choice.
