🚦 London — Driving Safety Gauge

Something that took me by surprise! I didn t expect a 50ish yr old Road Rager! On the Nottingham ring road on a part known as Valley Road. Chap in the Focus is going 30mph in a 40, obviously this is no crime but I did catch him up rather quickly. As we both proceeded along the ring road we approached an island, to which we both brake for, then all of a sudden he slams his foot down hard even though there is nothing directly in front of him. Anyway, no harm done as I was far enough away from him to brake well. But, why cover your brakes so that the brake lights are on then just brake hard all of a sudden, was he trying to cause an accident? Some distance passes before I am catching him up once again, as I get to around 30 meters away when he violently swings on his wheel and brakes, locking his front wheels and ending up in the inner lane, I pass him by and cannot believe what I see, he’s a respectable looking chap dressed accordingly, smart looking car and around the 50yrs of age mark. He stays close on my tail for the remainder of our route until he swings his wheel over again and pulls into the central reservation. What was all this about? Is he just one of those old chaps that are a nice decent guy until placed behind the wheel of a car then turns into an 18yr old hot head? The standard of driving on our roads is really starting to put me off. If I had the choice of using public transport to get to work, I would!
