If you ride with me, please do not hit my engine "kill switch" at red lights.

Recently started some group rides from a FaceBook group I am part of. We have about 8-20 riders, maybe more, on rides around the area and touring. Some people in the group think it is funny, to hit your "kill switch" at red lights or just before the light turns green. Okay, it was funny the first time, but then you you have a few that do it over and over again. We talked to them and said this is not cool, but they play it off and keep doing it. Not only is this a total annoyance, but is a safety issue also.Why do we have idiots on this planet! Thanks for hearing me vent. via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/8vkdhu/if_you_ride_with_me_please_do_not_hit_my_engine/?utm_source=ifttt
