All of my houses have had two-car garages. Until a few years ago, I always had two cars (three when I was married -- and a boat). My current garage could easily hold a full-size Mercan truck. My MINI has about five feet in front, and six feet behind it when parked.
A garage for my cars has always been a top-priority. I'm a car nut.

My brother collects rare motorcycles, nothing extremely unusual, just ones that had low production numbers and that catch his fancy.
When he got divorced, he lived in his truck (with his dog) for a couple of years, occasionally sleeping at friends' and family's houses, and when the opportunity arose, he bought a few acres off our grandmother, and proceeded to design his house.
We have an Amish-owned building company nearby that will take your sketches and turn them into proper blueprints and cut all the lumber, and that's what he did.
Besides a few other oddities, he designed his living room to basically be a massive garage. Proper garage door on one side, insulated to minimize heating/cooling loss, a custom double-door entry (no center pillar), so he would have the option to ride a bike right through the front door, and a poured cement floor covered in industrial rubber.
He put a line of metal shelving units down the middle, to sort of distinguish between living room and garage, and had several bikes on one side, and his sofa, TV, and a little wet bar on the other side. He was forever grateful when I dubbed it "The Liverage," (combo of living room and garage).
A few years later, he got married again, and...all that came to an end.
