California is one of the most visited stats in USA, it is visited by millions of tourists and visitors every year. These visitors rely heavily on rental cars for their travel needs. The tourists rent cars to drive around, but unfortunately they are not familiar with the area, its local sightseeing attractions etc. Tourists from other countries may also not be aware about the traffic laws of the country. They may not be comfortable driving the latest cars with new technology. It may be difficult for them to drive a new vehicle and also manage and adjust the side-view mirrors, the seat positioning, GPS and radio controls etc.
The above mentioned reasons can make the situation vulnerable and the visitors may end up getting involved in rental car accidents.
