I was scared to drive in Jamaica. But seriously, it's no problem mon. Stay to the left. You get used to it quickly. Follow the car in front of you, just not too close. Do the speed limit, they will pull a tourist over. I have been there, done that. Last trip I got my rental for the week for 180 bucks. I pay about 140 for my private airport transfers both ways. Was very convenient to have a car to run down to hilo, or drive out to the west end, or just go exploring.

Also drove to PA from negril from honeymoon. If you can handle Negril to Lucea.... you're golden. It's literally the hardest part of the north coast. After MoBay, it's basically as close to a highway as you can get.
