I think live with it, and be proud of your culture. All cultures have negative and positive aspects. The UK is a tolerant society by and large, but our day to day culture is shallow, and we're overridden by celebrities and the like.
I like Asian cultures, since even though they're less tolerant than the UK, they're mnre traditional and have better cuisine.
I think perhaps find some middle ground. Say to your mum that you would like some time to have fun, and that it's too stifling to stay at home a lot. It would show your mom that you're mature, and can handle the issue civilly. Also, get some of your friends to carpool, since this would make it safer and reassure your mum.
