It's not that, marz, it's the implication that such cyclists should be so singularly focused on their training that they aren't concentrating properly on things around them to such an extent that they are oblivious to anything other their intent to train as fast and hard as physically possible, at that moment, and that this then justifies why they aren't able to interact or communicate with others....
How far are training cyclists prepared to take this attitude about their speed, stage timing and funnel vision? ... does it circumvent the requirement to indicate for turns, slow for possible hazards ahead, look around them, make allowance for others in their way, or, god forbid, give way, stop or slow down. I appreciate that this is patently nonsense for the majority but where do training cyclists sit on this scale of nonsense?
