Slowing Down Saves Money and Lives, Manville Says

Associate Professor of Urban Planning Michael Manville was featured in an Atlantic article about the benefits of driving slower. Fast speeds use more energy to cover the same distance, making driving fast more dangerous, more harmful to the environment and more expensive, especially with the recent increase in gas prices. According to Manville, the first step to altering the culture of fast driving is simply to enforce existing speed limits more consistently. “If a camera catches everyone who speeds on a road segment, every time they speed, then you can actually get meaningful deterrence,” he said. Furthermore, speeding fines would be less expensive if they caught every instance of speeding. “The logic behind the high fines for speeding right now is that you don’t catch most people who speed,” Manville explained. However, if drivers knew they would be consistently penalized for speeding, they may slow down, a decision that could save money and lives.
