Technically I most of the houses on our (new build) estate have 4 parking spaces. A double garage and double driveway. Some of the houses have 6 parking spaces (a double garage and a drive you could fit 4 cars on). And there are a couple of houses that appear to have triple garages (with attic conversions, complete with dormer windows) making their garages bigger than many people's houses.
However, hardly anyone seems to use their garage for keeping their cars in. We don't put our car in ours either (but we've only got one car and a double driveway and DH would rather store crap in the garage). Lots of the garages seem to be converted into gyms instead.
The houses are pretty big so there are a lot of 3+ car households. The parking areas where you have several of these many car households who don't park in their garages are a nightmare. It's like Tetris watching people getting their cars in and out every day and worse at the weekend when their visitors try to cram their cars in too (rather than using the on-street parking).
There's a (hilarious) residents FB group where mostly people complain about: parking, people driving too fast, the traffic on the main road, and (my personal favourite) teenagers walking through the estate to get to a nature reserve on the other side.
The parking complaints are particularly hilarious because there are a group of people who hate anyone parking in the street. There are some parking bays on the main road but you could also park anywhere that doesn't block a drive as it's just a road with no parking restrictions. I think these people take the stance that parked cars make the estate look untidy and that they make it harder to drive along the road (presumably these are the people 'tearing around in their cars' that some of the other people complain about).
However, some of the anti-street parkers are very cross with the non-garage parking multi-car owning households due to the parking Tetris issue. The ones that keep quiet about that are presumably anti-street parking non-garage-users making them particularly unreasonable.
There's another group of parking weirdos who insist that they cannot use their driveways because they must park defensively on the street to prevent their children being mown down by the people driving too fast. I suspect many of them are secretly not wanting anyone else to be able to park outside their house. The two groups get quite angry with each other.
It's a joy. Truly.
