stupid drivers cause so many more crashes than speeders.  yes speeding can be dangerous, but id say about 70% of speed limits in the us are bullshit, and speeding can be done safely, going 10-20 over on a 75mph highway with low traffic can be totally safe, but going 5 over through certain city streets and neighborhoods can be dangerous.
people not paying attention, texting, hogging the left lane on a highway, going below the speed limit, taking turns overly slow etc... are all way more dangerous than the average speeder going like 10 over.
i got caught going 25 over and took a safe driving class because it made my fine and points go way down.  and it was cops who were teaching the class,  and they even said that almost all the crashes they see are from people not paying attention, hogging the left lane, causing faster traffic to come up on them fast, or have to change lanes into the slower right lane,  talking on their cell phones etc...  they even said that they would rather see someone speeding and paying attention than someone going the speed limit but driving poor.
i swear if we just made our drivers test a little bit harder we would have soooo many less deaths.  there are so many dumb fucks out there that are no where close to deserving a liscense.  instead of a 5 minute cruise around a neighborhood make it a month long process of highway, city, and mountain driving, and teach car control both in the dry and wet and we would save thousands and thousands of lives.  and then let people speed all they want.
