Another Aussie here. A few years ago I lived on a property about 20 mins out of town that was absolutely crawling with huntsmen spiders. One time I had just left work at night when I saw a medium sized spider crawl across my windshield. I freaked the heck out, watching it run back and forth across my windshield as I tried to find a place to pull over. After driving for a few minutes I pulled into a supermarket carpark, and was waiting for it to run towards the other side of the car so that I knew I could get out without it jumping at me. I was looking out of all of my windows trying to work out where it was when I noticed there was another fucking spider. Slightly smaller than the first one, but this motherfucker was IN the car with me, curled up on the shoulder of the front passenger seat. I have never been so utterly terrified in my entire life. I still had no idea where the original spider was, but there was no way I was staying in that car. I took my chances and bailed out. I had a minor freakout in the empty carpark before I mustered the courage to deal with the situation. Turns out the spider inside the car was dead already, so it wasn't too hard to deal with. No idea what happened to the first one though. Then a couple of weeks later my bf at the time came and stayed with me for a few days. As we were unloading his bags out of the car I opened my rear passenger door which was almost never opened as I rarely had more than one passenger, and was about to reach into the car when my heart just about stopped for the second time that month. In the hollow space between the interior and exterior of the car there was the biggest spider I havr ever seen in my entire life. I mean, it was MASSIVE. It could easily have been at least 15-20cm across.
