Dear drivers resident in the City of Pittsburgh:
Contrary to popular belief, it does indeed snow here–in fact, it does so every winter. Therefore, there is no need to act as if you’ve never seen frozen water before the instant a flake hits the pavement. By all means, take appropriate precautions; begin your braking a few feet sooner and moderate your speed if the road conditions appear to warrant it. Please note, however, that the appropriate precautions rarely include travelling at 5 miles an hour on a road that is merely wet, and that some people inexplicably fail to appreciate your zealous attention to making sure that they cannot endanger themselves by passing you in an area in which it is legal to do so. If the problem is that your eyesight is so impaired by falling snowflakes that you cannot make out the lines indicating lanes, perhaps you may wish to refrain from driving under such conditions.
