I live in a city of 60,000 people in Colorado. The closest train station is 15 minutes away, by car. There is a bus that will take me to the train station, but it’s an hour to walk to the closest one and the bus comes once an hour, 6 am to 7 pm, M-F. I can’t afford to spend 4 hours on a quick trip to the grocery store and never leave my house on the weekends.
There are bike lanes on the main roads (4-6 lanes 50+ mph traffic). More than half the vehicles around here are massive jacked up trucks and SUVs. I have a bike, but do not have a death wish. It regularly snows, making bike riding a no-go for most of 4 months of the year.
I am very much in favor of reducing car traffic. But it’s not feasible for so many people with the way cities are designed and the lack of public transport.
Keep the garage door closed for free heating in the winter.
