That’s 30 min of light exercise, five times a week — less if you are using electric assist. It’s the minimum requirement to not be considered sedentary, which would triple your health risks.
If you think that’s too much and you don’t have a serious physical handicap, you are about likely to have one.
I used to live in a hilly, rainy part of Germany. I cycled that exact distance every day. It's not an issue. If you've got children, get a cargo bike with child seats or a bicycle trailer with child seats. Works fine, many parents did that.
You need very convincing arguments to convince people to downgrade their quality of life that much. Biking on the rain uphill with a bike trailer is not fun compared to driving a car.
I would love that this argument about the quality of life to be also heard when talking about people who have to suffer the consequence of cars: violence, children's deaths, pollution, noise, aggressive tone, inhospitable cities, enormous parking lots that are hellish all Summer and don’t let water seed though. For the last years, deadly heat waves, and floods.
Selfishness isn’t an argument when making collective decisions.
If you've got dedicated bicycle lanes, then “it costs 10x less and you save 2x the time because you're not stuck in traffic” quickly becomes a winning proposition.
I don’t live in France anymore (too many taxis were trying to kill me, and the Police said they were powerless to help after ending up at the hospital multiple times), but my family still does.
Nine nephews and nieces, tenth on the way. The house is on a sharp hill (12% gradient) and the nearest train station is… 93 km away.
