(Driving a car no-hands is probably safer than riding a bike no-hands because at least you can use your knees to steer the car. If you want real excitement, just bicycle amongst cars where the drivers are going no handed. "Weee, I think I am going to become a hood ornament...")
That gave me a flashback memory....As an 8 yr old, sitting next to Gramps in his 37 Packard & steering while he used both hands to light a pipe! Eventually, he left a lit pipe on his workbench & burned down the garage with the Packard inside. He gave up driving because he disliked the new(1948) cars. Don
