As someone who recently obtained his, much later life... I also lived in a major metropolitain area. I didn't need a license.
Let me tell you, it's a lot easier to do so when you are still young, while your brain is more plastic, and your reaction time is faster. Maybe you won't use it much, but it's always nice to have. Easy to garner good will from friends... You can split long drives for vacations with friends, you can DD if you find yourself in a situation where the driver is intoxicated and you are not, if you become a home owner you'll be able to rent a van to go get materials at the home center, etc. You never know what life throws at you.
Trust me, just do it! You don't have to change your lifestyle because of it, but you'll innevitably find moments where it will be really useful to have!
