Do you drive a car? Do you live in the suburbs? Do you own a house? If so, these people hate you and insist you sell your car, move to an apartment in the city, and get on a bicycle while your town gets redesigned into a dense concrete nightmare.
There isn't an exact name for these people, the closest one being urbanists. But they are always identifiable when they bring up things like walkability/cyclability, public transit / alternative transit, and urban planning, want to start or move to developments like 15-minute cities, transit-oriented development, and mixed-use neighborhoods, and hate on cars using terms like car-centric/car-dependent/auto-oriented, urban sprawl, missing middle, car sewers, stroad, traffic violence, and a whole bunch of other terms you'll get to know if you talk with them long enough.
In short, these are the people who bought into the climate change hysteria about fossil fuels, and then gradually found more and more reasons to hate on cars.
