I would love to see separate lanes for buses and cars. In Hawaii, where I live, there was a proposal for an elevated, bus-only, viaduct that ran the length of a major freeway. This would have enabled buses that run as frequently as trains and are unimpeded by rush hour traffic, and are cheaply and easily scalable with demand. Instead we're getting an elevated train that has disrupted traffic already with its construction, that has blown through its budget with no end in sight, will be stopping short of its original end point due to cost overruns, and is only expected to reduce parallel car traffic by 2%. Ugh.
