Question what is stopping you from not using a car to commute?

I’m curious to know what physical or mental barriers might be preventing others from walking, biking, using an e-bike, or taking public transit to work. I live in West Ashley, just 4 miles from my downtown office, and I commute via e-bike. It adds about 10 minutes to my commute, but I feel like I save so much time by avoiding traffic. I’m really interested in understanding what factors, aside from obvious ones like weather, might be holding others back from making this shift. Thanks in advance.
