Is it worth learning to drive?

Context: I'm 25, I've never had a driving lesson in my life. I can't currently afford a car, nor do I really need one. I probably won't be needing a car at least for the next 2.5 years.

Are there any benefits, financial or otherwise, to learning to drive now, as opposed to waiting until I need to? I'm thinking insurance premiums, being able to rent cars etc.

Edit: Also, if you think I should learn to drive now, any tips on how to do it as cheaply as possible? ps. I'm in the UK.
