Wow, this is a vry timely post for me. A very young co-worker of mine was killed in an accident a few weeks ago. He was on his motorcycle, which he loved, waiting to make a left hand turn when a semitruck hit him from behind and killed him. He was doing everything right, riding safely and had his helmet on, but there was no way he could have lived. I was in an almost identical accident as a passenger in a car when I was the same age as him and I felt lucky to have survived when I saw my friend's destroyed car the next day.
Sadly, we can all drive as safely as possible, but there are other drivers on the road who do not and unfortunately, being on a motorcycle makes a driver more at risk.
As an extra note, I do not live in the Chicago area any longer, I am in Ohio now. However, when I was in Chicago, my boss' husband owned a motorcycle shop. She informed me that her husband had seen so many people injured and killed in motorcycle accidents that he actually did not ride any longer, even though he owned a motorcycle shop.
I wish you luck. I know that we can't control our husbands (or our kids in my case), but maybe if you are able to help him find the right or enough information he will make a decision that you can be comfortable with as well. My brother rides a motorcycle even though most of us are uncomfortable with it. His wife is an RN and knows the dangers, but he has so far been undeterred by all of us. Unfortunately all we can do is hope and pray for him.
