I am, without trying to sound arrogant, much better at cornering, roundabouts, and general driving than a large part of the population in Australia.
I can enter a roundabout, in a preselected gear, at appropriate revs and speed. Load up the suspension just right, so I'm released into my chosen exit, kissing the apex with a release of energy that feels so sweet, smooth and safe, that it's a beautiful part of my life.
All within safe thresholds, and always when I know it's safe. And the way others use roundabouts, it's always safer than the general population.
As a fellow Australian I think this is partly down to the equipment as well.
I can take a roundabout much faster and more confidently in my sports car with a low centre of gravity and performance tyres compared to an SUV with cheapo tyres like a large proportion of the population drives.
I'm guessing you also drive a car which is more performant than most on the road.
No matter what you drive, it's still not hard to be better than all the people who stall traffic because they don't realize they can squeeze through a gap about 4 feet wider than their car so we can actually pre fill the turn lane while the light's red.
Nor is it hard to actually know to accelerate smoothly through a turn instead of braking through it.
Or to know how to just stay in your clearly marked turn lane during your turn (literally marked through the entire intersection) instead of cutting off the other two turn lanes (this happened to me yesterday).
None of these things are actually much harder to do in a large car than a sports car, just obviously your actual speed and acceleration should change based on your car, tires, and everything else. I use the same principles I use when driving a fun car to help drive safely when it's a minivan.
I'm an American who knows how to properly signal when going through a roundabout. This automatically makes me more knowledgeable than 99.99999% of American drivers.
