Some things which have always annoyed me about the original panels:

• People walking cannot go nearly as far as they can on a bus or in a car, and any kind of real distance travelled is very slow.
• Public transit is also much slower than a car, door to door, when taking into account the first and last legs to get you from your start to public transit, and from public transit to your destination.
• People on a bus must all go along the exact same route.
• Most people in the US do not live where there are robust public transit options.
• In dense urban areas, lots of people from all walks of life make use of public transit.

Don't get me wrong, I'm all in favor of public transit, more of it, and in more places. But, fuck, it's not the travelers' fault that it's not always the best option (or in suburbs and rural areas, often not an option at all).
