I think it's a bad trend. Most cars only have one person in most of the time. If you have kids then there may be an excuse. I really liked our old Zafira that could take 7, but was not huge. I also liked my Hyundai i10 that was fine for commuting and easy to park. We do have a Honda CRV, but it's 20 years old. Still runs fine.
I think it's worse in the US where lots of people drive huge pickup trucks. It turns into an arms race where people feel threatened by bigger vehicles. There ought to be more tax penalties on big cars.
