why do you do this?
is there an actual reason to do it?
Driver in front with this habit affected me the other day on a single carriageway road, because some of the traffic lights (we went thru) were short-duration on green, another car could have got thru junction in the time available, or at least it felt that way.
There was Good visibility, no one being aggressive, all level ground so no worries about cars slipping backwards, nor frantic lane changing to accommodate. The driver in front just did this habitually, they stopped with a big gap between them & car in front. My car is 12' long & could possibly fit within some of the gaps they left.
