To play devils advocate - If I was that guy and I had scared these people off my property I would not be then getting in to my car and trying to mow them down. I would probably go back in and check on my partner who is apparently in the very very early stages of pregnancy.
Possessions can be replaced but lives can’t. This guy has ruined his own life due to what some could perceive as a short temper.
Agree whole heartedly a 22 month custodial sentence is ridiculous and it’s a joke the 2 guys avoided a prison sentence due to injury, but the guy should have just taken a second to realise chasing after these people in his car over a failed burglary is a moronic idea.
