I am sorry for your loss
I don't ride motorcycles. However, I would like to add my two cents from a different approach, if I may.
I am a runner. I usually run at night, but sometimes I run in the morning. I always expect, when crossing the street or running in the street (which I try to avoid), that I won't be seen. Motorists aren't looking for motorcyclists, runners, bikers, etc. This varies, depending on the area you live in to some degree I believe. I always try to make eye contact with drivers when I can. Otherwise, I yield to them.
What I find so scary is the ever increasing motorist who isn't going to see me or you because they are texting or reading or talking on their phones. I am too too busy to research this, but I would like to know to what extent accidents have increased due to the use of phones over the last 10 years.
I saw a lady texting on her phone, with her children in the back of her suburban, drive onto the curb, almost hit three kids walking on the sidewalk, but missed them because they were able to jump out of the way. She swerved back onto the road... and then started texting again.
