When I practiced at a driving school, the modified controller was heavy and difficult to operate. When I learned about the hand controls, I didn’t immediately buy one either. I wasn’t sure if I could actually drive. Once again, after experiencing the hand control at a driving school, I decided that it was removable, the price was affordable (I can understand even if I didn’t use it), and the brake accelerator operation was light. If you bring it to your parents’ house, you can operate other cars and it is versatile
