Anyone who has driven along mountainous roads in snowy conditions knows how difficult it can be to drive uphill. As long as the traffic is moving, there’s a good chance you’ll make it up the hill. But the minute traffic comes to a halt, the advantage you used to have changes because you no longer have momentum in your favor. Getting your vehicle to move uphill from a full stop in the snow often results in spinning your wheels and just not making much progress. The same is true of a safety-culture change.
