We don't have enough of it. We're literally on top of one another. Heaven forbid developers and city planners from allocating more than two inches of park space per 1,000 families or more than three meters between apartment buildings. Even the big American superstores that have come to Israel undergo a transformation. Even at rush hour, when traffic crawls, no one tailgates.
Psychological space is the deeper difficulty.
We relentlessly intrude on each other's lives. There's no refuge of calm from the cauldron of ideological conflict. Some people don't have enough room on their cars for all the political bumper stickers they need in order to shove their pet perspective or multiple perspectives up your nose. We're not content to believe in things. Israelis are compelled to project their beliefs into every last corner of the public space.
