When picking up the vehicle, a deposit of approximately NT$16,000 will be pre-authorized. This will be fully refunded immediately upon return, which is very quick. Remember to fill in all driver and passenger information completely before picking up the vehicle to avoid wasting time upon arrival. You must bring an international driver's license to use it. For a 2-hour trip, it's recommended to only follow the blue areas on the map. The GPS only has English pronunciation, but it's very easy to understand, and the navigation display is clear and simple. If you accidentally go off route, don't panic; just turn back onto the correct road at the next intersection, and it will resume navigation. Overall, it's like riding a motorcycle (a three-wheeler), so Taiwanese people will have no problem with it. We had an exciting and fun tour of San Francisco's streets with the kids. Highly recommended!
