During the paperwork process, the Hertz agent from Asia had a constant smile but also tried to persuade me to buy additional insurance and even encouraged an upgrade. Even though I had already purchased full insurance, he still claimed that I didn’t have roadside assistance. After repeatedly emphasizing that I had bought all the necessary insurance, he finally directed me to the car lot. Be cautious, as this is another potential pitfall. There were about five or six different cars parked, but only two of them were actually available for me. The others required an upgrade (if you accidentally took one, you might get stopped when leaving, wasting a lot of time). After taking several photos and confirming repeatedly, I finally got my car (there was no Ford Focus as I had reserved). Instead, I got a Kia Forte, which turned out to be nice to drive with lane-keeping assist. Driving from Los Angeles to Las Vegas was stress-free. American drivers are very disciplined, making the experience very enjoyable.
