I will list the aspects in my chart involving the 3rd House and give a description of my driving habits.
In my chart, I have an unaspected Mars Rx at 24d 58m Scorpio in the 3rd House and ruling the 3rd and 8th House and Saturn Rx in 13d 25m Scorpio conjunct the 3rd house cusp by less than 1/2 degree, which opposes the Sun and sextiles Jupiter. I have Mercury Rx in 28d 03m Aries in the 8th House which conjuncts Venus, trines Neptune, and opposes Pluto, modern ruler of 3rd House in the 2nd House. I also have South Node in Sagittarius in the 3rd House.
Currently, I have a clear driving record since early 2009, but my first year of driving, I had two accidents due to failure to yield. First one was due to gliding past a blinking red light because I got distracting by two other people in the car, and second one was due to a white car cutting me off causing me to clip a van (ticket for this one was dismissed in court). On the first ticket, the cop cut out the fine.
In March 2006, I got a speeding ticket while I was following somebody to a restaurant. I had lost him so I decided to speed up to find him again. A cop happened to be sitting on the side, and I flew right by him. He reduced the ticket on the spot.
Overall, up to age 24 or so, I was often a fairly fast and hard driver on average. Hard driving, however, has always led to greater costs in maintenance and repairs. When driving with others in the car, I am usually slower and easier, so I have always been known as a good and safe driver. Presently, I driving more smoothly.
2006 was the year I did the most speeding. At the time, I had a '91 Plymouth Sundance RS where I did some modifications (mostly air intake) to make it faster, and I would often drive very fast on highways and back roads. At times, I went 100 MPH on two lane roads. The fastest I got up to was 120 MPH. My car had an automatic transmission with a floor-mounted gear shift lever, and I would often shift it like a manual transmission.
In 2000, my first year of driving, I also did some crazy stuff. For much of the year, I had a '91 Oldsmobile Cutlass Supreme Quad 4, and that thing would GO! My friend (he has a Mercury Square Mars in his chart) and I would often race people in it. Unfortunately, it had electrical problems that were difficult to diagnose, and we had to sell it at the end of the year. I got the Sundance right after that, and it was much more reliable.
I've always noticed that anytime I am approaching a high speed while driving at night, and I see an oncoming car on the other side, I always seem to assume for some reason that it's a cop. So, I slow down. Also, everytime I see a car that is a Crown Vic or a make/model that cops drive most often (particularly if it's the same/similar color), I often assume it's a cop.
I notice also that I have quick reaction times when driving.
I've never had problems with road rage in my years of driving so far.
One thing I have tended to up until recently is cruise around leisurely and kinda aimlessly. If I don't have a destination in mind, I will tend to go to a place that I didn't originally plan to go.
