You don’t know they were going as fast as you stated. And if they’re suddenly caught in it….the best they can do is ease up and let it slow by friction. Trying to brake could cause big swerving which could take out more than just 1 car (not just the front car) in an instant.
The point is if this happens suddenly you can’t blame them for “going at a high rate”, since they didn’t know this was coming.
Yes, I do.
