I drive a non-sporty sedan from early 2000s. It isn't a "cool" car by any means, although due to various reasons, I drive around typically at 1 AM.
Over the 5 years I've been driving. I've been pulled over maybe 30 times. In Australia they always collect a sample of your breath, ask where your heading, sometimes a drug test.
I've never been pulled over for any driving infringement. It has always been because 1AM is "suspicious".
It is a waste of my time and their time. We have neighbors who just moved in and every item was stolen in the house on the week of their move in. They called the police and not a single police officer showed up at the house. None of their items were ever recovered. It's hard to have respect for police when they try their hardest to not do anything which requires an ounce of thinking or investigating.
