According the last 100 years of climate alarmists, we've been underwater and on fire simultaneously...yet somehow we're still here arguing about spark arresters...I mean.... can you take a fire steel and start a fire easily with kindling you find anywhere nearby, at any time of the year? Additionally, is climate change trending towards drier weather?
I don't think it's necessary on most of the bikes, but we did have one guy set Oregon ablaze by trying to burn his TP that one time so I'm going with "people are stupid, engineers are trying to safeguard against the stupidity."
