I know about the spikes, I'm aware.
Regarding chases, laws here are similar, with one conjunction to Australian ones - they don't chase bikers. Only bikers can chase bikers, and biked police is basically non-existent (very rare). Also maybe I'm not taking into account one other thing - that your criminals there in the US are clearly insane. An aftermath of a completely shattered system. My entire life - I never saw a chase, and I only saw one on the TV - once in my life. Murders rarely happen, and even if they do happen, the killer just surrenders 99.9% of the times.
Still I would never support trigger-happy cops on power trips. I don't argue there are good people but most of them suffer from PTSDs and leave the police force to become firefighters or private security advisors. The ones that stay - are the pure psychopaths and sadists who got bullied by their dads and in school.
Another thing I want to mention before I go to bed is this - it's completely not normal to have a pig chase you down because you just drove near a speed camera with 30 km/h over. Here you will never get chased for "over the speed" violation. It's a very perverse system that sends in you in jail for speeding, testing your car, racing, whatever. In Germany and most of Europe, it's even allowed to drive without a speed limit on the Autobahn.
I think your laws need revisement, to become softer, and your criminals need to have perspectives because they never get rehabilitated. Just look at Denmark or Finland for example. They've done a pretty decent job. Their violent criminals become CEOs and their jails are like hotel rooms, with TV, internet, even smartphones and knives.
And Australia just needs to be tougher on deportations and border patrol must be upgraded
