Weather

Jessica Fletcher is the main character of Murder, She Wrote. She doesn't drive and lives without a car in the fictional town of Cabot Cove, Maine. Wikipedia says the first-season episode "Murder Takes the Bus" establishes that Cabot Cove is just north of the town of Newcastle.

According to Wikipedia New Castle, Maine has dreadful weather:

Average annual rainfall: 49 inches.

Average annual snowfall: 78 inches.

And mean daily temperature is below freezing three months of the year.

Positives: She's a retired school teacher who has become a writer and she lives in a small town and bicycles locally and takes taxis when visiting places like New York.

I'm a writer by trade. It's the kind of thing where you aren't punching a clock at an office or similar. That's probably typical of people who live without a car in the US. Most are retired and/or "societal drop outs" who don't have hard charging standard careers.

Negatives: Most of the series was filmed in California and I don't recall ever seeing any snow in Cabot Cove, or even rain for that matter. Furthermore, these days really tiny towns frequently lack essentials like a grocery store and you may have no bus or train service to get in and out of town without a vehicle.

And the series really doesn't account for dealing with the weather when you live without a car. It also doesn't really address practical matters like getting enough groceries home by bicycle, even just to feed one person.

Reality: If you live without a car and are fortunate to have flexibility because you do something like writing, you do a lot of planning your day around the weather.

You often run errands when there's a break in the rain or when the temperature gets warm enough on a winter day. 

If you are familiar with the bus routes and have two options on a rainy day, you may choose your route based on having good shelter at the transfer point. 

Some European country has a saying that translates to "There's no bad weather. Only bad clothes." You may need to update your wardrobe some to account for walking or cycling out in the weather routinely for things like grocery shopping and not because the weather is nice and it seems like a good day for a stroll.

You may find yourself checking the weather a lot more than you did when you drove.

Your interpretation of climate data will change over time. You may live someplace that gets a lot of rain, but perhaps it's mostly at night and hardly interferes with your daytime activities and you sort of laugh at what people say online who drive everywhere and don't make those extinctions.
