Since November 2015, new HGVs have fitted with the following safety devices: automatic emergency brakes, adaptive cruise control (matches speed with vehicle in front and maintains the gaps) lane departure warning, and all round proximity sensors. Since the week began, I've seen 5 rear end shunts, watched countless cars drifting out of lane, tailgating galore and conversely failure to maintain speed on gradients. I love the new kit, it's saved my life twice this year and done wonders for fuel economy.
