> in a low density light industrial zone In a city with excellent public transport, you get a segregation effect - jobs that don't require (many) vehicles (office work, much of consumer retail, certain kinds of light industry) build up in areas with public transport links. Then industries that do require vehicle access (warehousing, heavy industry, builder's merchants, trade buisnesses) build up in areas without public transport links, since they're cheaper than those with access. At an individual level driving to your office or training to a warehouse might still work or be necessary, but at a population-level it happens less than you'd think.
