Actually, I really like this analogy because
1) We can’t really work on non-trivial fixes for our cars because they are too complex
2) We’ve totally structured our living situations around these over-complex beasts
3) Sometimes they do just break down at random, and it becomes a mini-crisis for everyone involved, which can’t really be resolved without missing a day of work to go to a professional
4) The bike is in exactly the same situation, except you can actually fix most bike problems yourself with a little kit
And yet, it is seen as a serious adult thing to have a car, instead of a bicycle.
Some thoughts:
Outside of, like, customer service, most places are throughput-oriented and it doesn’t even really matter all that much if somebody misses a day.
If we really cared about “uptime” of employees, we’d all be living in bicycle range of our jobs, and able to fix our bikes. Maybe there’d be a bus route as well.
