Stopping distance in a car is therefore 140.22 ft.
Do you think that you can’t do equal or better on a bike?
Any situation that you believe a car can do safely, there’s no reason to believe a bike couldn’t either. FFS we have these wonderful things called motorcycles. Much less contact with the ground [than a car], much higher speeds. Works just fine.
If you look at that page carefully, it gives the full formula for the brake distance. And assumes a factor of f=0.7 for an average car.
The AASHTO gives a factor of f=0.25 for a bike. Which means: Yes, there is a difference.
The f for a motorcycle is somewhere in between, but nearer to the .7 than the .25.
