Prison is not supposed to be somewhere you can't cope, that isn't the point of it, the point is to take away your liberty, thus making that time wasted and your future life more difficult, that is the punishment element of prison.
This professional driver "simply didn't see" - rather he failed to look properly.
The defence has a little dip in to victim blaming, " he asked the judge to consider his client’s culpability in the context of the crash, pointing to the fact Mr Mallinson had not been wearing reflective clothing or using flashing lights. He suggested the cyclist was ‘very difficult to see’."
So it's careless driving, rather than dangerous and careless rarely carries an actual custodial sentence. Yet again to prove dangerous driving in this case would have been very hard, so the CPS and judge were tied.
Cycling UK is pushing for the starting point of dangerous driving to be any action that would be an immediate fail during a driving test. Killing a cyclist would be an immediate fail.
