Even if you don't plan on driving it's still a decent idea to learn and get a license. You never know when you might need to apply those skills and it might even come in handy when applying for work.

You should learn to drive regardless; you never know when you're going to be called on to drive a friend's car or need to hire a vehicle to e.g. move house.

I've had to teach several people in their 20s to drive through lack of opportunity or willingness when they were younger.

I don't feel comfortable about being in control of a heavy vehicle moving at relatively high speed.

A car is not a heavy vehicle. :)

I know I'd drive over a pedestrian the first month because I got lost in my thoughts and completely forgot to pay attention to being in a damn car.

You won't.

Additionally there's the high prices of gas to consider, low prices of bus transport, and for me as a student non-existent prices for trains.
Why pay extra to create additional traffic and kill people?

Knowing how to drive doesn't mean that you'll immediately go out and buy a car, then start exclusively using it.
