No, Linda - I do not impede traffic in the left lane.
Am a 'safety conscious driver'. Tail-gators infest no matter which lane one drives in.
I also keep FOUR seconds of distance from car in front- two seconds is insufficient reaction and braking time, given the number of traffic weavers that cut in and out constantly. One weave can cut time to less than one second - and with two second distance - a problem develops - and all of a sudden one does not have sufficient distance to avoid a collision.
Four seconds infuriates some of the hot-heads - but frankly, I don't give a damn. My life and property are worth far more than their idiocy.
Most folk respect the distance, and in fact, start widening their own following distance.
