Catechism references on speeding
2290 The virtue of temperance disposes us to avoid every kind of excess: the abuse of food, alcohol, tobacco, or medicine. Those incur grave guilt who, by drunkenness or a love of speed, endanger their own and others' safety on the road, at sea, or in the air.
1809 Temperance is the moral virtue that moderates the attraction of pleasures and provides balance in the use of created goods. It ensures the will's mastery over instincts and keeps desires within the limits of what is honorable. The temperate person directs the sensitive appetites toward what is good and maintains a healthy discretion: "Do not follow your inclination and strength, walking according to the desires of your heart." (Sirach 5:2) Temperance is often praised in the Old Testament: "Do not follow your base desires, but restrain your appetites." (Sirach 18:30) In the New Testament it is called "moderation" or "sobriety." We ought "to live sober, upright, and godly lives in this world." (Titus 2:12)
