It's here! I love it! This morning was my second commute to work in my new GTI(pp) and I've noticed that my driving style has definitely changed.
Driving a 1.6 TDI I was having to really put my foot down to get any expression from the car at all and would often cruise along the motorway at a slightly higher than average speed.
With the GTI though, it's that knowing of what you have and how you can use it that puts the smile on my face even before putting a foot down. Cruising at 65-70 is absolutely fine because if I want to overtake someone then I can at the blip of a throttle.
So yeah, I think fast cars are definitely safer given the right mindset.
In fact that reminds me - the only time I got a speeding penalty was when I moved out of an ST and into a Polo rental for a week. Took so much effort to get going that I ended up screwing up!
