No. I live in Florida and I don’t feel like owning a car is under attack. Where I live it is a golf cart community, so a lot of people use golf carts to get around instead of cars, but still there are plenty of cars driving around, and plenty of people in my state who have more cars than people in the house. Also, in most places around the state there is plenty of parking, where I live in particular there is always space available, except for major events it gets a little tight sometimes.
I lived on Miami Beach for a while years ago, and even there I could find parking, but it was a little less convenient, more urban. Parking garages and street parking.
Florida charges a lot to first register a car, but then it is cheap to renew registration. Some states, like North Carolina and Virginia, charge property tax on your car every year, so to me that is a deterrent.
Edit: I should add that I think it is a failure in my community that we don’t have convenient public transportation, and a problem that my community is so spready out. I love where I live, but that is the one thing in the model that I think is bad design.
