Low-Fidelity Driving Simulator Training in Parkinson's Disease.

The goal of this clinical trial is to learn if low-fidelity driving simulator training works to improve cognitive performance, driving behavior, and driving aptitude in individuals with Parkinson's disease. The main questions it aims to answer are: * Does low-fidelity driving simulator training improve cognitive performance? * Does low-fidelity driving simulator training improve driving performance? * Does low-fidelity driving simulator training improve driving aptitude? Researchers will compare driving simulator training to no-training (waitlist control group) to see if the low-fidelity driving simulator is effective in individuals with Parkinson's disease. Participants will: * Undergo 10 sessions of driving simulator training or be placed in the no-training group. * Training group participants will visit the driving simulator lab 2-3 times a week for 4 weeks for training. * Paper-based tests and driving simulator tests will be done before and after 10 sessions of training (or a waiting period).
