Google’s annual I/O developer conference brings about 5,000 attendees to Mountain View, Calif., for three days of in-depth sessions on all things tech. This year’s event will omit one notable feature: parking. Starting last week, Google let ticket attendees know the 2019 conference is a no-cars event.

“In an effort to reduce traffic congestion and reduce our carbon emissions, Google I/O 2019 has committed to be a ‘No Parking Event,'” its website read. It’s a big change from previous years, when close-in parking was reserved for attendees. This year, the closest parking will be 13 miles away, with exceptions for disabled attendees. The company says it will increase frequency of shuttles from train stations and hotels, as well as from San Francisco, San Jose, and Oakland. They’re also offering free Lyft and UberPOOL shared-ride services via promotional codes, along with free parking for bikes.
