Hypothermically cold/wet days, if you suffer a physical injury, going anywhere with friends, trips to IKEA, groceries that last more than a week, vacations, or the reason I stopped cycling:
a car driver randomly forces you to pay for a new bike while also giving you a concussion and 7 stitches to your face then drives away.
Happier now with my 'cage' than with the ego I used to have.
I got through a full year before giving up and buying another car. I have never been motivated to repeat the experience, though I still love city life and try to keep car usage to a minimum, getting around primarily by motorcycle.
And obviously there are tremendous use cases to enjoy weekends, do groceries/other shopping, helping friends and family and so on and on...
I come from Europe, currently living in Switzerland which has best rail system in the world and general decent public transport... but still owning a car is a must for 4 of us, travelling anywhere with kids is a chore and amount of stuff for weekend is impossible to carry in public transport (stroller(s), child bed, all clothing, food equipment etc. and thats just kids).
Sure you can spend all weekends in the same place if thats your thing, but it certainly ain't ours, not when we have alps just in the backyard.
When the weather's sufficiently bad, we take the BMW with heated seats instead =)
I don’t think this happens before mom and baby are discharged from the hospital, so it is not relevant to the discussion.
That said: my wife and her mother _did_ ride home on the back of her father's bicycle after she was born (in 1980s China).
Better tell the people in the Netherlands they can't ride bikes then!
