Now that I have begun driving, I have seen alot of things that many do, and don't consider wrong, while driving.  One of the most common of these is speeding.  Speeding can be a sin, if done intentionally, because by speeding excessively, you endanger others' lives.  That is why we must always try to drive the speed limit.  Another thing I commonly see is a lack of charity on the roads.  I see many get angry over the simplest things.  We must learn to accept that no one is a charitable driver, and not be mean to them.  When we see someone who needs to get in our lane, let them in, or if someone does do something wrong while driving, what I like to think, is that maybe they are driving their wife to the hospital to have a baby, rather than, they are just a stupid idiot who has no idea of how to drive, and saying uncharitable things, and giving uncharitable motions.  Another matter is drunk driving.  This is even more serious that speeding, because it oftentimes does kill or seriously injure another.  You can also seriously injure yourself, or other passengers in your car.  Be considerate of them, and you must also respect your own body.  Be considerate of others, and yourself, while driving.  God bless!
