The last mile issue can be addressed. It is already being addressed in Sorrento valley. I have a lot of coworkers that take the coaster in to work – despite the fact that the station is 3-4 miles from work. There are shuttle buses that take them out to our campus.
Forward thinking businesses offer these kind of services on their own, already. A friend works at Adobe in Seattle and lives on Bainbridge Island. Adobe offers free shuttle buses from the ferry terminal to their campus… and loaner cars for employees that want to run errands at lunch. It’s a sweet perk and my friend sites it as one of the reasons he will stay with Adobe long term.
When I lived back east near Philadelphia – the suburban campus I worked at was served by a network of shuttle buses that ran from a main bus terminal to the surrounding business parks. Friends swore you could not get to work by bus – I proved them wrong, on a bet, and rode the bus to work daily for a month.
If a community or business chooses to address the ‘last mile’ problem it’s easily solved.
