>> If we gave drivers some extra incentive to avoid the most congested hours, we could better utilize the roads’ capacities. There is already enough incentive, the incentive is to avoid seeing your hours waste away on traffic. Most people don't really get to choose their hours, with or without incentive, otherwise they already avoid the most congested hours. So the suggested incentive doesn't really make a difference when it's not a matter of choice, except by taking money away from people without adding any value.
