(Portland, OR) -- The Portland Bureau of Transportation is extending the deadline to comment on proposed automated vehicle rules. So far, more than 70 comments have been made along with in-person and virtual meetings. In 2018, the City Council adopted a rule for testing the vehicles. Now, AVs are being used in over a dozen cities with plans for deployment in at least 20 more cities over the next year. The comment deadline is being extended from April 4th to April 10th.
