As a motorist, and I do drive on a few occasions, I do take extra precautions to not be involved in any collisions. As I said earlier, the time you take to be cautious and defensive when behind the wheel is more than made up for the time you'd lose if you were involved in a collision when you are inattentive and reckless. I just keep that in mind.
As for cyclists, I am extra mindful of them, giving them plenty of space when passing.
