Despite the fact that antilock brakes are designed to make driving safer, research suggests that people who drive cars equipped with antilock brakes have more accidents than those who drive cars not equipped with antilock brakes. Each of the following, if true, would help resolve the apparent discrepancy described above EXCEPT: ['Antilock brakes require expensive specialized maintenance to be even as effective as unmaintained regular brakes.', 'Antilock brakes were designed for safety in congested urban driving, but accidents of the most serious nature take place on highways.', 'Most people who drive cars equipped with antilock brakes do not know how to use those brakes properly.', 'Antilock brakes malfunction more often than regular brakes.']
