Use public transport, take a cab if you need to or use a car club (shared vehicles use less resources than owning a car), ride a bike, walk the 10 miles. Infrastructure helps to reduce personal car use.
“But my quality of life!”
An umbrella solves that at minimal cost.
For the record, I don't think all car use is wrong, but the example of visiting a friend 10 miles away isn't a very good one. Someone shouldn't be expected to buy a car and its associated maintenance, tax, and externalities, just to visit someone that nearby.
I want to say here that this comment sounds extremely alien to me, to the point that out of context I would have taken it as satirical.
I know you're serious, but there's probably a big portion of people to whom discussing the problem of walking in the rain to the bus stop sounds completely ridiculous, in any context, and as as something we must consider when talking about climate change policy, well, even more ridiculous.
I've lived in rainy places, and you just wear a raincoat, boots, maybe an umbrella (not always), and carry on.
This kind of disproportionate weight assigned to even the smallest levels of personal discomfort, when discussing these problems, is what most people are denouncing here. And this bias might be what pushes people towards techno-solutionism that doesn't have a chance of actually solving our problems in the time frame that we need.
I'm also unsure what the proposed solution to Bob being 10 miles away is. Should I only make friends with people who work at the same place?
