Yup, everyone will have had different experiences. Growing up in Gordon Head, over 99% of our trips were made by car. Now, living in a condo close to town, about 20% of my trips are by car. Is this the case for everyone? Not even close. And the way our cities are built, having a car is a necessity for the majority of people, regardless of where they live, apartment or SFH.
Someone may be just as likely to own a car living in a condo vs a SFH (in reality, probably a tiny bit more unlikely, but we'll call it even for now). But if you're on a fixed budget for a house, you might be stuck with a condo closer to the city, or a SFH out in the suburbs. Sure, you might use your car for the same amount of trips, but the kms travelled will definitely be more for the SFH owner. That is where the big impact is.
