In this case I know he was trying, but I fully understand your point, had a similar experience I Germany playing with a very built mark 2 golf.
Tuned, catless turbo BMW motors blow a little black puff when pushing high boost and you floor it. My mini does it too, that, and you know he broke the back tires loose lol.
I don't blame you for being cautious.
If I had to endure all those speed cameras you blokes have in Oz, I'd be paranoid as well.
BTW - we call those fast cages "test dummies".
All cleaned up now. Great trip, longest 2 days on Mufasa for me. Trip averaged 37.5 MPG, the vast majority done between 80-90 mph, including quite a bit of play and mountain climbing. It's real, built motors get better MPG on the open road, crazy.
