One nice thing I've seen is on Brighton Ave in Allston. The road has one or two lanes of traffic each direction, and there is a "bike lane" going down the center of the rightmost lane. It's marked by dotted lines and has a bike symbol on it: https://www.google.com/maps/@42.3523473,-71.1263011,82m/data=!3m1!1e3 https://www.google.com/maps/@42.3523473,-71.1263011,82m/data... It's more or less a way of saying "yes dammit bikes can be here". But it works. Drivers are more respectful, and the road doesn't need to be any wider.
