That's the constant planning fight where I live, there's rarely enough off-street parking but the default would be to stop every development. Realistically any development puts more pressure on the already exhausted on-street parking. I don't think anyone in Surrey has heard of cycling (to be fair, we're on the North Downs, so you've pretty much got to have legs of steel if you plan to cycle, but I hear there are flat bits of Surrey).
I've told the story of the last place we lived, small gated private development of 12 four-bed houses, one parking space each plus a half-dozen guest spaces. The only way we could stop constant stupid parking was to physically block it with large planters with trees in. I mean, you've got four cars so you buy a house with one parking space? If you had four kids, you'd probably think twice about buying a one-bedroom house.
Cars actually *in* garages? On my street it is de-rigeur to convert the garage into another living room - or perhaps a play-den for the kids.
Actually, thinking again of the houses in question, only one does this, the others have garages set back enough that they use the space in front plus the pavement as a 'driveway.'
Our garage is full of bicycles and Ikea furniture – my wife has hatched a grand plan to turn it into a gym, which I'll leave to her. But we have two (ish), there's a 'tunnel' under the house where the car lives.
