I eventually got through yesterday evening, gave all the details and expect to be called back to make such a statement, I am determined to do this, as the guy could easily have wiped out some other road user and himself.
On another note. Being a witness some months back to an accident the guards took a statement from me. Didn't hear much for about 3 months then out of the blue two chaps showed up at my house looking to take a further statement. I wasn't in and when Mrs Bear answered the door she thought I was in serious trouble, I thought that was funny, she must think I have dodgy operation going on in the garden shed!!
