This a heart filled reach out.Your whole life the quest is go faster.Then as you start getting there and the raising costs per run and more importantly a honest concern for the driver a question pops up "what is too fast"??.Then if you think your going too fast,what next??.We I think all have been brought up to contently think about going faster,but if you think you have reached a limit that you shouldn't go beyond.Your comments are surely needed.
