I was just thinking (I know its dangerous for me) that todays vehicles are far superior and more powerfull than what came before, so therefore we should be able to use them at faster than posted speeds or to race someone or use them in a manner in which we feel is okay is similar to saying rifles are more powerful so lets use them for reaching out farther. Whereas I think one could make the point that all the manufactures set out to do was to make them more reliable and to do there designed job at the normal hunting range more efficiently, and offering up something that would allow you to get the job done quicker and deadlier to alleviate any suffering on the part of the animal. Just a thought, and yes I have taken some longer than average shots and as long as one has the skill I guess who am I to say they shouldn't.
