I've been asked to discuss the practice of some drivers who "slow down, way back from a stop light, potentially blocking access for both the left and the right turn lane, especially where there is an advance green light for a left turn." The person who requested the examination is irked by these drivers as it costs them precious seconds of driving time.
I will admit from the start that I am one of those drivers who watch what is going on around me and anticipate what is going to happen at the intersection. If the light is not green with the traffic moving smoothly in front of me I will gear down or let up on the accelerator and try to change my speed as evenly as possible until we are back to speed and flowing freely again. It is something I've watched the truck drivers do over the years and have finally seen the wisdom of.
Driving in this manner reduces the wear and tear on my vehicle. I'm not waiting until the last instant to stand on the brakes and come to a halt increasing the risk of a collision if I misjudge. Neither am I having to always start from a complete stop which contributes to my fuel economy and lowers my carbon footprint.
