I feel like this is a conversation that takes place in every single household the first day a kid gets his/her license...
Parent: Just make sure you be careful out there. Fasten your seatbelt. Look both ways. Check your rearviews. Don't....
Kid: ....how come you don't trust me?
Parent: It's not you I am worried about, it's everyone else on the road.
Well, I don't want to sell the loving Mom's and vigilant Dad's of America down the river here, but that last response is nothing more than a heaping load of horseshit. Of course your parents are worried about you. It's the first damn day you've been put in charge of operating a motor vehicle - that can double as a deadly weapon - on your own. They aren't worried about the rest of people out there that have been driving cars for years and know the unwritten rules of the road like the back of their hand. They are worried about you, and it's not because they don't trust you to pay attention to what's going on around you, it's because they know you're likely paying too much attention to what's going on around you.
Look at this video of A$AP Rocky for instance. He's got his hands 9-and-3, his dick grinding against the steering wheel, and he looks like he's about to start sweating profusely. I bet he's more nervous driving that car right now than he ever has been the seconds before putting on a live show. That apprehension is what leads to accidents. Dude is just looking for a reason to prematurely press on the brake. No question he jerks the wheel the opposite direction if a truck passes by him just a littttttle too closely. Probably takes him a good 15 seconds to change lanes when there isn't an oncoming car in sight. New drivers are more likely to drive scared, and driving scared is the main cause of abrupt horns and sudden unnecessary movements. I guess what I am trying to say to all those teenagers out there is that no, your parents don't trust you, and it's likely because you drive a lot like a trap rapper...and not one that's merely faking it in a music video.
