I am in mixed minds about this sentence.
The accused got delayed and then irate about not being able to pass a cyclist. He then overtook and left-hooked him, leaving him laying in the road needing 16 stitches, before phoning the police once he was settled in at work.
Mostly because driving away from the scene is the (imho) lowest and most heartless thing any individual could do.
But it does at least go some way to being appropriate.
I know that some of us would like to see hanging for similiar crimes

but what are your thoughts on the approprateness of the sentencing in this case, especially when compared to others that you have seen\heard about.
There is much to admire in this sentence, but I think it can be improved in some areas:
The compound verb 'got delayed' is slightly colloquial in structure and might be replaced by the construction: 'was delayed'.
Similarly, the (implied) construction '... got... irate about not being able...' is slightly inelegant. It can help to read sentences aloud before submitting them.
The word 'laying' as applied to the sentence is transitive in use and must therefore alays have a direct object. I might perhaps have been laying the table or laying my sword on the ground. The construction '... leaving him laying in the road...' might be improved by using the word 'lying'. Hence: 'leaving him lying in the road'. The confusion between lay/laying and lie/lying (as a verb, participle or gerund) is not uncommon, as the former forms a part of some past constructions of the latter.
Taking the positives from the sencence, one can say it avoids ambiguity and shows an admirable economy of words. The grammar might be polished a little, but all in all I think the sentence is not a bad one.
I hope this helps, although the thread might be better placed on a 'Use of English' Forum.
On a slightly more serious note, I was at school in the 70s with the chap whose death caused the birth of the charity 'Roadpeace' to address inequities in the response of the law to deaths and injuries caused by reckless and dangerous driving on UK roads. I believe Roadpeace may still exist, although the founder may now have little to do with it.
The dead man was riding an XT550 near Tower Bridge when an Escort van RLJ-ed and he caught it amidships. He died at the scene. The driver of the van got a £250 fine (as I recall it) and no mention of the death was made in court.
This was many years ago (1991?). The situation now is way, way better. We will all wince sometimes at what look like inappropriate sentences, but the wheel is slowly turning in favour of victims.
