//I cannot believe the responses.//
Then you should not have posed the question!
//In 1) the driver ran his car over the woman and failed to stop. Anybody else think that 40 hours community service and 8 licence points sufficient?//
As with many things legal, the devil is in the detail (much of which we do not have). If he was only charged with failing to stop, that explains a lot and your astonishment should not be one regarding sentencing, but regarding charging. (Once again, you don't have the detail - or the evidence available - to know why that decision was made).
Failing to stop is one of a comparatively very small number of driving offences which can attract a custodial sentence (the maximum being six months).
Looking at the sentencing guidelines:
https://www.sentencingcouncil.org.uk/offences/magistrates-court/item/fail-to-stopreport-road-accident-revised-2017/
And bearing in mind he was given eight penalty points, the court obviously thought this offence fell within "Category 2". A community order is compatible with an offence of that seriousness.
Just for information, if he pleaded guilty and had the court decided to impose the maximum sentence (6 months) he would have served just four weeks in prison. He would be entitled to a one third discount on his sentence, thus reducing it to sixteen weeks. In serving that sentence he would have been automatically released at the eight week stage, but as well as that he would be eligible for "Home Detention Curfew". This means he would have been released after serving just 28 days.
The press reporting of this incident is clearly designed to engineer the maximum outrage possible. It seems to me this was not a case of deliberately mowing down a pedestrian. Apparently she collapsed in the road. But I'm not going to jump to the conclusions the press would like me to. Only those in court will know the full details and without them outrage is a bit pointless.
