Isn't that an argument for CR's test? They explicitly drive 1hr between each braking test so that it's not just "accelerate up to speed as quickly as possible and try again".
- sliken 8y agoI dug for information like that. I only found "Our automotive engineers conduct a series of brake tests from 60 mph to a standstill on wet and dry pavement to measure stopping distances." Do you have a reference for the 1 hour between brake tests? My reference is: https://www.consumerreports.org/cars-how-consumer-reports-tests-cars/ https://www.consumerreports.org/cars-how-consumer-reports-te...

- cjhopman 8y agoAh, it's not 1 hour, it's 1 mile. It's in the article. Still clearly not "accelerate up to speed as quickly as possible and try again". "As its name implies, CR’s braking test is meant to determine how a vehicle performs in an emergency situation. The test is based on an industry-standard procedure designed by SAE International, a global engineering association. Our testers get a car up to 60 mph, then slam on the brakes until the car comes to a stop. They repeat this multiple times to ensure consistent results. Between each test, the vehicle is driven approximately a mile to cool the brakes and make sure they don’t overheat."
