Me and Judy (QD) park bikes at a church in Daytona twice a year. I cant even tell you how many bikers we have to push or jump because of the kill switch stop. Many of them claim they were taught to do this in bike school (MSF) I have been through the basic and the experienced rider and I dont remember being taught to use the kill every time I stop. If they are doing that now, I can only assume (hope) they mean while in the course so you get more used to where the kill switch is.
For all you that think you will never forget to turn the key off. I carrry jumper cables in my saddle bag. But, I may not be riding with you....be careful out there. IMHO get used to the key again and reduce the risk of being stranded

PS. this also goes for the ones that look so cool zooming up and popping that kickstand down to kill the bike....then walk away with the headlight burning.........happenes every trip
