Well I guess it could be argued that someone can tailgate responsibly too?
The only \"lane spliting\" I know of that is legal is when two motorcycles ride abreast. Never knew of a state in the US that allows passing between two vehicles on the deliniator line as a legal manuver. If there is one I would like to know the state? That is too close at any speed. I also don't remember anything in my cycle safety course that suggested that lane splitting is a safe method of riding.
I have had cyclists not riding with me, pass me in my lane. Would anyone suggest that this is responsible driving?
I would never wish anything bad to happen to a fellow cyclist. However, given the inherent disadvantage we have when something goes wrong it seems to me to be irresponsible to come in such close proximity to other vehicles at speed for no compelling reason. And I have been in traffic where the cars around are too close for comfort because people don't keep safe distance and made a manuver I normally would not make, that is weighing necessary risks. But I do not ride between cars on the line.
If my comments are taken personnally by other members then maybe they should think about it a little longer and consider their family, freinds, and others and not just themselves before playing thread the needle.
