On the other side of this, one of the reasons MC riders use to rationalize lane splitting and filtering up at red lights, is the concern about air cooled MCs overheating if they are forced to sit idling in stop and go traffic. If that is not a real concern then there goes half their argument to allow lane splitting.
You and anyone else is of course free to turn off your engines in traffic, but I was making the point that often riders need to carefully decide if the situation even warrants what may be overprecaution measures. Personally, I care more about my safety than I do about "degrading" my oil.
I wanted to address your point regarding lane splitting, especially as a rider who has split lanes legally here in California for some 3 decades and none of it was done to keep my engine cool. Studies on lane splitting have shown that riders that split lanes are less likely to be victims of being rear-ended.
Riders who split lanes to come up to the front of the 'pack' at a red light are reducing their risk of not only being rear-ended at the stop, but it also allows them to pull ahead of the pack of cars that are all a risk to the rider. The less you are surrounded by vehicles, the less you are at risk by them. The practice is safe as long as the rider isn't 'jumping' the green light or speeding to keep the 'pack' behind.
Another concern people rarely address in the debates on the topic is rider heat exhaustion. The first time I ever split lanes was in a situation where I was stuck in miles of bumper-to-bumper traffic during a horrifically hot summer in Los Angeles California. The heat was radiating off the pavement in waves and off my motorcycle engine, and I was sitting in it with full leathers and a full face helmit. Sweat was running down my head, back and chest and it was like some kind of torture to sit there inching along. Finally, I saw other riders riding past me as they split lanes and from that day forward I split lanes whenever it was safe to do so. Splitting lanes that day could have saved my life had I passed out from heat exhaustion right there in heavy traffic onto pavement you could fry an egg on.
Lane sharing is relatively safe if done in a safe manner. Southern California freeways are some of the worst congested in the world and I've split lanes through them safely for over 30 years (almost daily to & from work).
Of course there are going to be idiots who split lanes recklessly, just as there are always going to be riders who ride like fools. People in vehicles should be more tolerant of lane splitters if they realize they are reducing their traffic congestion and reducing their risk of being rear ended. Many California drivers are totally tolerant of lane splitters, often pulling over for them as they approach and getting a 'thank you' wave from the riders (I get this all the time).
At one point, our Highway Patrol even posted tips on safe lane splitting, but then they wimped out when there were complaints that this was encouraging riders to split lanes: (https://www.dmv.ca.gov/portal/dmv/detail/about/lane_splitting)

I'm obviously an advocate for the freedom of riders to safely and legally share a lane, when doing so reduces rider risk, congestion and heat exhaustion.
