I just spent a week in New Jersey. It was not possible to get anywhere without a car. I had to take a lot of Ubers from my hotel. Surrounded by large multi lane roads and car parks. No pavement to walk even if you wanted to. Every business needed a huge car park. Everything was incredibly spread out.
Maybe this is normal for Americans, but for me it was a car hellscape. I don't own a car living in London, and there just isn't the same need.
