I know a guy from Mich that had his leather jacket come loose that was strapped to his seat that got into the rear wheel. He knew some was wrong and when he seen what was happening he tried to pull the jacket free while riding, well just like that it pulled his hand in causing him to leave the road going into a ditch and striking a series of small trees. Not good..... Cut a fuel line and ignited setting the bike on fire. Worst part of this was he was trapped on the bike with his badly mangled hand caught in the rear wheel. He was severely burned on his upper torso and neck area, had his thumb almost severed and was put in a induced coma for 3 weeks but survived. He was riding a softail custom on a country road not heavily traveled but luckily a lady and her daughter seen him go off the road and stopped to try and help put out the fire till rescue arrived.
Sure wish he had just pulled off the road and stopped to remove the jacket as this accident change his life forever and is dis figured and on total disability from work.
