The number of people who live in such a situation is a rounding error in the population of L.A., though. It’s also a strange response to my observation that it’s a really short trip if your car A/C doesn’t have time to get cold.

That's a badly designed town. You should be able to do your shopping within reasonable walking distance - you know you want poor people to not need to own a car, you want health conscious people do a little bit of active travel when they need groceries

I live about as far from a supermarket as you can in my town, so two are each about 5km (3 miles) away, with both having a small collection of shops, and the supermarket occupying less than a quarter of the centre

I also recall watching a video from one of the Nordic countries on the subject of cycling in winter

Their method: wear warm clothes

They had an advantage though in that loads of people ride there
