If I can't see, feel, breath, hear, stand up on my own, walk a straight line (without falling down), pay for gas, remember where the keys are, or how to fire up my spyder, I may not ride and just go back to bed. However, into day's world your FOBOs and instrument cluster are going to go through your manifest for you, providing your batteries are all up. From my long ago days of dirt biking none of the above were enough to keep anyone from riding. Someone was always ready to share gas with you and nothing but a flat tire could stop you, unless of course you were in second place, and then a flat may not even slow you down. If you don't think any of this is true, just text my wife and ask her. Even if my wife was in the hospital and I was in charge of the kids, they all came along and worked as my pit crew and then they took turns riding two up with me. Well.......that last part was somewhat of a truth twister. If I or my wife were in the hospital I'd probably not ride. But, the kids playing pit crew and riding two up with me happened more than just once, when my wife wasn't around. Seriously though, common sense, that little Jiminy Cricket in your head will keep you safe if you listen; and that goes even if you are standing still or moving at what seems to be light speed. Just be safe out there and watch out for the safety of your fellow riders.
