Teslas zooming through a tunnel? Battery-powered shuttles gliding over roadways? Autonomous mini-trains delivering you straight to your destination?

With one of the nation’s fastest-growing airports and a booming development scene in and around its downtown core, San Jose is taking a renewed interest in its longtime goal of creating a transit system to connect some of Silicon Valley’s largest attractions and employers, mostly along the Stevens Creek Boulevard corridor — from De Anza College to Main Street Cupertino and the Apple headquarters to Valley Medical Center to Valley Fair and Santana Row.

About a year after the Valley Transit Authority and the cities of San Jose, Cupertino and Santa Clara asked companies to submit proposals for innovative transit modes between Mineta San Jose International Airport, Diridon Station and destinations along Stevens Creek Boulevard, a consultant hired to evaluate the proposals has released its findings.
