Absolutely false. You're mathematically safer when your speed is at parity with the other drivers on the road, and stopping unnecessarily interrupts your moment

Absolutely false. You're mathematically safer when your speed is at parity with the other drivers on the road, and stopping unnecessarily interrupts your momentum to the point of drastically reducing your average speed over the course of a given distance traveled, increasing the chances that you'll get more severely injured during the journey. If a car is travelling at 35 mph and you're traveling at 25 mph, then the relative speed of the car is 10 mph. If a car is travelling at 35 mph and you're travelling at 10 mph, then the relative speed of the car is 25 mph, which is going to hurt a hell of a lot more than being hit by a car travelling 10 mph relative to you.
