If you above me, why do you like poo?

my parents still make me wear a car seat harness and I'm 14 i started off with the normal car seats and then got the britax traveller from which I outgrew they then got me a model 28 harness but I kept escaping from this if it got to hot in the car I now have a model 31 houdini harness I can't escape from this one until they let me out of it it has straps over the shoulders around the chest and waist and between the legs I can't escape from this one until they let me out of it it is highly embarrassing because every morning and night at school they have to strap me into it and release me from it in front of all the other kids and the fact it has a strap between the legs which makes it look more like a baby harness has anyone any advice please I don't know what to do I also think its dangerous as I would be unable to escape in an emergency
