I've commuted via pubic transport my whole life, I have a driver's licence but don't need the extra expense of a car, although I know commuting in London is far from cheap whatever the method.
I'm sort of used to it anyway, I see it as 45 minutes in a morning and an evening where I get to read a book, the news, listen to some music. I try to make it time not wasted as it all adds up.
Occasionally you get some hefer sat next to you who crushes you against a window or someone who makes you want to gag because they smell, but you gotta take the rough with the smooth! Its a better way to get to work than driving anyway, occasionally I get a lift with my cousin and he is stressing at traffic and looking for parking and I just don't see the convenience of car travel to be honest. I'd be stuffed without my ear phones and a book though, they are a must, I actually appreciate the time to myself. Thats not to say I couldn't real off a list of thiings that piss me off on the bus though, miserable bus drivers being top of my list, with teenage honeysuckle backs thinking I want to listen to hard house blasting out of their phone speakers and inbreds with dangerous dogs happily letting them jump up and lick petrified elderly people worth an honourable mention too. What you have to tolerate is when little kids are on the bus crying and people get annoyed, my philosophy is its public transport and open to anyone to use, learn to live with the fact kids exist or buy a car.
I worked out that since the age of 21, I have travelled about 6,000 times on my local bus service at 45 minutes a time thats 4500 hours 187.5 Days or just over 6 months of my life sat on that bus!
