sometimes i can be very unconfident when driving.  i guess it was how i was raised to look at cars: "a vehicle is a weapon."  that little lesson came from a variety of family members and it never left my mind.  when my dad got into a near-fatal car accident two years ago, it was very scary for me.
consequently, i'm a defensive driver, but i don't like driving very much (new york may have something to do with that).  when i drive to work, i'm usually in the left lane of the parkway and trying to follow, but when i lead, i'm going a good 15mph over the speed limit and it scares me at times.  besides that, i follow all road rules to a tee, almost.  i almost stop longer than expected at stop signs, since they're almost always in congested residential areas.  i signal and i never follow too closely (i HATE it when people tailgate me, especially when i'm already going above the speed limit!)
