Please report dangerous drivers to the police - Roadsafe. Report to plod, not just whinge here.

I'm not familiar with the sentencing guidelines for GBH and / or dangerous driving, and the sentence may well have been at the top end.

The question become, therefore, was the charge appropriate, and should the pustulant fucksack have been charged with a greater offence, such as attempted murder.

Pointing a 10 tonne speeding steel machine at someone strikes me as a deliberate act, and you have to expect that doing this is likely to kill, or maim at the very least.

The guideline for assault is here
http://sentencingcouncil.judiciary.gov.uk/docs/Assault_definitive_guideline_-_Crown_Court.pdf. I'm assuming its section 20 GBH so page 8.
but without all the facts it's difficult to figure out which category he would have fallen into - but must be 1 or 2. Then impact of guilty plea would have reduced the sentence by up to a third, and I guess a charge of dangerous driving would be served concurrently as both offences arose out of the same incident.
Think it would have been difficult to prove he definitely tried to kill the guy, so GBH probably reasonable as a charge that would stick rather than try attempted murder and then not get anywhere with it.
