| 118. And thus pesky reality intrudes :-) |

It would also take twice the pressure on the brake drums or rotors to make twice the braking force. Something that might not be achievable.
I've seen some pretty impressive skidmarks on the highways, but you are correct. There weren't 18 of them!
From the car magazine I read, it looks like most passenger vehicles stop in about 170 feet or so from 70 MPH. I don't know what I big rig does, but I would imagine that, fully loaded, it's somewhat more.
