"Road debris is something I take very seriously. In the past when driving on the freeway I have had my car hit by a lug nut that came off of a big rig (made a huge dent) and I had an entire sheet of sheet rock/drywall flip up in front me when the car proceeding me went over it. It exploded like a big ball of snow when my car went through it. On top of this my wife had a large piece of wood come right through her front windshield. I wouldn't be caught dead driving my Slingshot on the freeway without a helmet even a small rock could be devastating if it hit you in the head."
"...................though not before (her helmet) saved her from serious injury when road debris was thrown up and clobbered her just above her visor....................... I will agree with the sentiment that wearing a helmet should be by choice, but it was very fortunate that Justina chooses to wear a helmet for I could have very well lost her that day."
Yep, and how about an added experience of where I happened upon a swarm of bees while riding, the front, wind screen and my helmet took hours to clean. I honestly do not know what to say to somebody that would actually laugh and make fun of somebody that chose to wear their helmet while riding the SlingShot?
