Actually the biggest commuter ferry routes in the Seattle area can be drove round. Ie Kingston and Bremerton are on a Peninsula and Bainbridge Island is connected via the (short) agate pass bridge. The idea of more bridges has been brought up but met with strong "not in my backyard" resistance. A short bridge from Bremerton to Bainbridge would make a lot of sense (and allow two ferry routes to be combined) but the wealthy Bainbridge Islanders are against being connected to the less well off Bremerton.
