I"m in favor of raising the age for full driving privleges to 18. Its not a matter of 18 year olds being better at keeping the car between the lines, its that most 16-17 year olds lack the maturity to make intelligent decisions about when they should be driving,taking risks, etc. I could go for letting 17 year olds drive between 6 AM and 11 PM, or something like that, so they can get to and from school, work, football practice, etc.
I don't buy the whining from surburban parents that their kids need cars to get to work, most of them are working
