I'm thinking of getting a motorcycle but?

So here is a quick summary of why I came here. I live in California in SoCal and I am 16 years old. I have been had a fascination in motorcycles since about 4 years ago when I came across Jake TheGardenSnake on YouTube and have since found almost 7 other motovlogers whose videos I always watch. Ever since I found Jake I've wanted to get a motorcycle but I figured I would wait until I got my license before I told my mom (I don't live with my dad) that I wanted a bike. So in pretty much 1 month I'll be able to go take the test to go get my license (for a car of course). It was just the other day though that me and me my mom were coming home from a trip and I was driving and she told me that I need to always be extra careful of motorcyclists when driving on the freeway cause they can come out of nowhere and you might hit them. She then said something along the lines of she wouldn't want me to get a motorcycle because she would be worried I could get in an accident and get hurt. Now this is pretty much a big slap on the face for me. There is one other thing I want to say and that is that I have absolutely no experience on any type of motorbike so yeah. How would you say I could persuade my mom into letting me get a motorcycle?
Added (1). I was thinking of getting a dirt bike as my first bike since they tend to be durable and I could probably drop the thing a few times since I have no experience. The bike in particular is a 2015 Honda CRF250L. Do you think this is a good choice?
