Aggressive, dangerous driving, yes. Uncontrolled anger by the van driver that risked serious injury or worse for the cyclist, yes. Behaviour that deserves prosecution and custodial sentencing, yes.
Attempted murder, no. Hyperbole risks undermining the seriousness with which such behaviour should be treated.
Yes.
I'd be pretty sure (and his defence lawyer would agree) that he had no intention of killing.
It was clearly
feasible to kill the rider with that stunt - if a death
had resulted, then I'd support a Manslaughter charge.
So I suspect it's merely assault. (if the rider was unharmed then it can't be ABH or GBH.) You can get quite a stiff sentence for assault, with a tailwind. If you do it with your fist, or a baseball bat, or other items less lethal than a white van ...
