Driving around a roundabout into feeder lanes that merge coming off it and cars in turn merge with no issue.i merge behind a truck and this car aggressively pulled alongside me and sped in front then slammed his foot on his brakes.i did an emergency stop causing my grandson to fling his head forward in his car seat plus my daughter and her friend to panic.couple of mins later the truck driver shouted abuse at me as I’m guessing the two vehicles were together as went same direction.
Male dark hair and glasses but didn’t see great deal of his description as the sun shone on my eyes
