As a biker for 35 years anything we can do to make ourselves more visible and safe is a good thing IMO.
Car drivers ability to see us ain't getting better IMO.
In 1998 and 2007 I had major SMIDNSY caused by blind car drivers (one driver even claimed as he was also a biker that he couldnt be at fault despite numerous witnesses!) They were low speed ie sub 30mph and I was wearing full leathers, gloves and lid but that didn't stop broken bones, nerve damage, permanent limp and metalwork insitu for the rest of my life.
Was it in the 1980's advert for kids walking home "be bright be seen".
It holds for us too.
Ride safe all.
