Drivers with no slip road etiquette or ability to anticipate. Driving west and picking up speed, from the Hermiston Gate roundabout in the inside lane with a car about 30 yards, if that, in front of me and no cars behind, two or three cars in the outside lane about to overtake me and the slip road to my left, apparently, empty. Out of nowhere, at a rate of knots, a car steams up the slip road, past me and jumps into the space in front of me and has to brake hard to avoid the car in front. With nowhere to go, I’ve got to brake violently to avoid going into the back of Lewis Hamilton. To add insult to injury, within a second or two, he accelerates and sidles into the outside lane, causing the drivers in that lane to also slam on the anchors. No signals at any point from the muppet. Fortunately everybody reacts well and the incident is over in seconds with Lewis disappearing into the sunset, with a huge grin on his face, I’m sure. I hope, when he has his next accident, he performs a crazy manoeuvre which doesn’t involve any other road users.
