I don’t think the size differences are as drastic as that. An opel Astra hatchback is 4374mm long and 2062mm wide, while a Volvo XC90 is 4950mm long and 1923mm wide. As long as they both fit comfortably in a normal parking space the dimensions are not going to contribute meaningfully to more congestion or other inconvenience.
In the Netherlands I often see people with Dodge rams that are noticeably wider and longer than every other passenger car. If this was a large or growing category I can see myself being inconvenienced and annoyed more
