You start learning to drive a year before you can get your license meaning they would have as much experience in the car as a 16-year-old if the age was raised to 18. So saying that they would be more comfortable is a false statement. What you think is people should learn to drive sooner and gain more supervised experience and lessons.

We shouldn't change to driving age because that wouldn't make a difference. One article says sixteen-year-olds crash more then eighteen-year-olds but that isn't a fair argument because eighteen-year-olds have more experience in driving then a sixteen-year-old so raising he driving age would make new drivers older and with as much experience as the sixteen-year-old had. Therefore raising the driving age is not the solution to the problem here, so we should keep the driving age as is and find a different resolution.
