If you don't like the laws where you're at - move. That's what any adult would do to change that situation.
If you were here, you'd barely be able to get registered to go to driver's school. Sure, you're 18 and you can take over the world

Do what you can, finish school and if you need to, find a different hobby to tide you over for your time there. At least, that's what us adults do when we're not where we can have our usual comforts. Have fun and enjoy your time in the UK.
