So carrying on from the is lane splitting dangerous thread I thought I would pose a question on ethics. With lane filtering I feel ethically obliged to do so. When I filter to the front of the queue both I and the vehicle begin at the same time. Due to my acceleration capabilities I pose no loss of time to those between the beginning of the queue and those where I started filtering from, while those behind gain time because there is a net loss of 1 vehicle to wait for. I reduce travel time for everyone behind me and offer a net gain for society as well as offering myself real gains on time. Its win win. However with lane splitting I no longer pose this benefit. If I'm passing moving cars I am now splitting to a point to which the traffic starts moving at a speed I am no longer comfortable splitting and then I reenter traffic. At this point the vehicle behind me slows down to accommodate me costing them and every vehicle between there and where I begun splitting 1 vehicles wait in travel time. Here I have no longer benefited society but taken from it for my own benefit. Now this doesn't stop me from splitting but I thought I'd put it up for discussion. I argue that my net benefit offered from filtering more than makes up for my net takes from splitting. Then again I spend a lot of time splitting, I split for about half my commute every day. Thoughts?
