THis Volvo has amazing brakes i know i drove one myself ,the newer types have some sort of brake assistent that makes an emergency stop when it detects something when it gets to close in front of it.This one was probaly not heavy loaded or empty
It's an good system on the other hand i don't know if you know the idiots who want to take an exit just before you and hit the brakes,the Volvo reacts to that as well.I've seen footage of another truck who drove in the back of the volvo's trailer,just imagine what would've happen if there was a car with family in it ..........
