Yeah, I appreciate that it's complex, but in the US we prioritize cars instead of people.
A properly designed system will account for lots of transportation options. This means:
- force cars to go around city centers - prevents gridlock in downtown, and improves transit and walkability/cyclability downtown; enforce with car-free zones
- buses and bike paths to connect the different parts of the city
- trains to connect cities
- highways and roads connecting smaller towns
If you go to smaller towns, a car is your best bet. If you're going downtown, a train should be more efficient, and a car should be workable. If you live in or near a city, a bike should be sufficient.
We used to have one car because I could bike to work, but now we need too, and only because of the 2 days I commute to the office. And the worst part is that there's a train line near my house that I could totally take to work if they actually built the line they've been talking about for decades. But instead of building that line (connects to a larger system, including a stop at a major sports stadium), we expanded a highway (didn't fix traffic) and we're building a new highway (might help somewhat). Most of those cars are traveling along the proposed train route (it runs parallel to the highway), yet the highway gets priority.
I propose we rethink transit in terms of moving people instead of cars.
