First of, there is a lack of Experience. Teens could be faced with challenges and dangerous situations and if they don't have the experience, they could be in serious trouble. Which means seriously injured. (This next example is kinda weak but I added it in case you want it) They won't have time to study. Driving with friends can make a teen irresponsible and they can totally forget about their school responsibilities.
Being 16 and driving is very dangerous. You should be atleast 18 or older driving for your safety! hope this helps! LMK if you dont approve i will resend :)
<span>The description of Old Scratch infers he's a demon.... particularly the "great red eyes". The fact that he is "begrimed with soot" alludes to the fires of Hell. Would he frighten me? Defintely.</span>
