Exactly this.
When you consider a lot of houses even built from 1920s-1980s probably only had parking for a single car, because that's all people had in those days. Whereas nowadays you'll find a lot of households (especially when children have grown up but can't afford to move out) require parking for 3/4 cars.
When we were looking for a house, parking was one of our top MUST-HAVE priorities. As i can only see parking getting worse over the next 10-15 years before driverless cars start to become the norm.
We even turned down arranged viewings on a number of houses where we'd do a casual drive by to check the house out and notice that the drive way was absolutely tiny - photos made them look considerably longer.
On the topic of parking, every house from my builder from their lowest 2 bed linked that I have up to 5 bed detached have 2 parking spots, and occasionally the houses with a single detached garage only have 1.
I had some people from one of detached houses ask me if they could use mine / my neighbours always empty shared 4 car driveway, I told them they could if they wanted to pay for it but then they didn't want to.
I then looked into listing it on 'park on my space' type sites, before realizing I wasn't allowed to rent it out on my shared ownership terms anyway.
So the two smallest 2 bedroom houses with neither occupants owning a car have a shared and empty 4 car driveway all the time, meanwhile said people that asked to use it for free have 2 cars on their driveway, 1 in front of their house, and a fourth parked at the side of my house on the opposite side of the road from them.
Then again if you have the need for more than 2 cars, maybe you should have looked for a different property with parking for 4 in the first place.
The driveway for my house is behind the property / garden too, so even if I did drive it would still be much more convenient to park next to pavement in front or at the side, which the other people with 4 cars are already doing anyway.
Been looking into if I should put a shed on my driveway, but being behind my property its not convenient for that either.
