Automatic braking systems save lives. Now they’ll need to work at 62 MPH

On a related note, I've always wondered if straight ahead 60 to 0 braking tests were relevant to anything. Not many accidents happen where a driver is just unable to completely stop and end up hitting the other car at 10 mph.

I would think the insurance companies could come up with a better braking test, like 60 to 40 with a swerve, where the suspension response factors in as well as both tire lateral and longitudinal grip.

A 60 to 0 braking test gives you a floor on the braking distance.

You've got to add safety factors from there. Reaction time, road conditions, vehicle condition, steering inputs, etc.

But also, a brake test with a swerve is going to be a lot less repeatable, because the driver input is more complex.
