Today I was driving on the country roads. As I've come to a junction to turn right I have stopped and waited for about 15 seconds until I seen it was clear to go. As I've gone a car has come whizzing around the bend at 35 - 40mph which caused him to swerve when he seen me so there was no accident. However, the driver of the vehicle then pulled over, waited for me to go past and he then quickly set off, over took me and slammed on his brakes right infront of my car, which could of caused an accident but luckily I'm a very aware and cautious driver so braked straight away and stopped my car. He came over to me with an aggressive manner and being verbally abusive, he pressured me into giving him my insurance details. This was my first time being in a situation like this, as I was on my own and intimidated by this man I stupidly gave them but didn't ask for his (I couldn't think because I was a bit shook up), there was no visible damage to his car that I could see but he accused me of scratching his tyre. He then said to me "you're going to f*cking pay for this, I'll make sure of it". I contacted my insurance company straight away and explained what had happened, I'm waiting for a call off the claims department in the morning. Would appreciate any advice for this matter!
