If by "hire a car" you mean car and driver, that would be something on the order of Uber. If you mean what is commonly called rent a car, which means drive it yourself, I would strongly advise against doing it unless you have done driving in right hand driving countries before, or you can dip your toes in the water with several short trips in light traffic with no time pressure before doing anything more. Your normal left hand roadway driving habits can get you killed if you respond by normal habit at the wrong time. Secondly, you need to be sure the rental car companies would even let you rent a car at all.
