This is debatable - Light Rail isn't always the answer, that is absolutely true, but in many places, it can alleviate traffic congestion, and in conjunction with other ride share services, can help immensely in all forms of traffic. Seattle has a major congestion issue and I5 is a mess all through Seattle, and you can feel the impact even in Tacoma during heavy traffic. A well placed light-rail can be extremely effective, for example the Hiawatha line in Minneapolis. It's not a panacea for infrastructure issues (I5 really is just trashed in most places around Seattle) but again, in conjunction with ride shares, it likely will serve a good number of riders.
