You don't enjoy driving your Cat!?!?!? It's not how fast you go, it's about how fast you know it can go by a simple push!
Ever since I started driving, including riding motorcycles which was first, I've pretty much driven as fast as humanly possible, and ideally sideways. Heck, I've had the Pete and its trailer sideways on a narrow dirt road, just because. That's how I figure I've worn out numerous guardian angels since I've lived to talk about it..
Obviously, with the 'Cat I can't drive anywhere near as fast as what the car is capable of, but I did try. But lately I don't feel anywhere near as invincible as I have been.
In other words, the 'Cat is still my favorite vehicle, it's just that I no longer enjoy always driving it at its/my limit.
