Like what everyone else has said, it doesn't make you a bad driver as far as car control, but it does mean you're not a smart driver. Again, as the others have said, no offense.
Now that I'm doing deliveries and have time working against me during the day, I drive more like an asshole than ever in the delivery truck (which is a Mazda B3000, so basically a Ford Ranger 3.0 V6, and what a pile of SHIT!!!). I'm frequently doing 70 in 45's, squeezing under red lights, I've drifted through dirt lots when I needed to turn around, and in one instance I was about 500 feet from the end of a school zone and I just said screw it and floored in the rest of the way.
However:
- The 70 in a 45 is a road that is kind of a backroad that no one takes, and there's never any cops. I could do 100 if I wanted, but I don't know if the truck will get to 100
- The close calls with red lights, I've gotten real good at scanning the intersection first to see if there are any cops around and quickly make my decision from there
- The school zone... I had already come through it the other direction under the speed limit, so when I came through again, I knew there were no cops so I just went for it.
- The drifting through dirt lots, well, that's just for the hell of it
Part of it is knowing your town, and especially, where the cops hang out. There is a downhill corner on my way back from school, it can be quite fun at speed. But I never haul ass through there, because about a quarter-mile ahead is a known spot for cops to perch and check your speed. I've seriously come through that section at speed, with others staying with me, then approach that corner and slow down and watch the other people get caught
I have not gotten a ticket in 3 years (although I've received 2 warnings since then), and - knocking on wood desk - I don't plan on getting another one anytime soon.
