Especially when following the law that the larger the car, the less capable the driver.
I went to the philharmony last Sunday, and the number of people with large and expensive cars who were less than capable to park them properly in an underground car park was hilarious.
Parking spaces are smaller relative to the size of your car
Sitting high up with a huge hood in front means there's less visibility in front
Longer cars make it more difficult to judge distance using your mirrors, somewhat eased by the requirement for parking cameras.
Longer cars generally have a longer wheelbase, making a worse turning radius
The only saving grace as a driver is that heavier cars can be safer for their occupants, at the cost of everyone else's safety... which most would consider a negative.
