I totally agree with Tony, it scares the poo out of me when I'm on the motorway. I really hate it when they get so close to my car because if I were to break, the great big juggernaut wouldn't have a chance to stop in time. Having said that, there are many cars who are guilty of tailgating. In fact, when my baby was 7 mths old, traffic ahead suddenly breaked coming off a motorway, we heavily breaked in time because we had left a big enough gap for eventualities like this, but the car behind us crashed into the back of us and the car behind him crashed into the back of him! My baby was strapped to the back seat of the car in her carseat and luckily, was fine. The chap had the cheek to have a go at us for breaking suddenly and insisted it was our fault for breaking!
