My main problem with a commute is not that it's 30 minutes, but that it's 30 minutes by car. I despise driving. It seems like such a complete waste of time in general. Plus, it's dangerous dealing with a bunch of idiots on their phones. /rant over
In short, living an hour outside of London in a small village meant that the drive to the station (to take the train to London) involved rolling hills and long and twisted scenic roads. It was really enjoyable - usually my favourite time of the day - even more so if like me you are into your cars and bought yourself a nice car to enjoy it with.
On summer evenings after work I would find myself taking 1 to 2 hour detours discovering new roads and sceneries, usually until the sunset which at peak was somewhere between 9 and 10pm. It was the best thing I ever did for my mental health, but now I live in London it's not something I can do anymore. I walk to and from work through a very busy, stressful and polluted city.
Self driving cars still waste a lot of space, if they're only transporting one or two people.
