Ooooh Welsh bashing! Generalisations about races are just pants mate. There are as many rude, ignorant people in England percentage wise as Wales.
bot : TBH your reporting this incident to the Police seems a trivial matter, and whilst illegal, doesn't warrant the time and effort you put into it or the time and effort of a police officer dealing with it.
As for other videos, you don't need to hit something to be a dangerous driver either on a bike or in a car. Crossing the meridian for any reason should be judged for safety by any type of vehicle, but the amount you see it these days is pretty shocking, mostly due to lack of concentration.
