This is true. Commuting in an urban or suburban environment should be significantly easier than it currently is. Public infrastructure needs to improve and become less car-centric. That being said, if you live in a rural area or a small town where there is very little traffic, or if you need to pick up groceries for your family of 4+, cars are needed. People in anti-car communities do not like to hear this, but I do not think cars should be criticized for merely existing. Current infrastructure should be criticized for only considering them. I think that while holding on to the idea that car=bad is fun, it also sours people who genuinely rely on cars to the movement and limits what actual progress could be made by these communities to make walkable cities a reality. Thank you for listening to my ted talk.
It's extremely hard to nuance any conversation on any forum when multiple people interact. People almost always assume you're pro or anti something. It's also easier mentally to reject what doesn't match your views.
Debating on the internet is useless most times to convince the other party, but I'm sure some people reading it who haven't made up their mind on the subject can appreciate a well put out idea and maybe consider it before making up their mind.
My truck is used for hauling junk, supplies, tools, moving appliances etc. My job doesn't work without a truck. Can't get abandoned furniture to the dump on a bus. It is what it is.
Staw-man involves making claims that something is ssying something it isn't. Many of the posts I have seen and comments I have read suggest that the mere existence of cars is a problem. This is what I have a problem with because some people in rural areas, for example, need cars. I am not claiming that anti-car communities attack people in rural areas, rather, it can seem that way for those people.
Changing to a different form of transportation, unless it involves teleportation, is just moving the problem somewhere else. It might be all electric, and it might get you there twice as fast, but you're still just leveraging a tactic that moves the goalpost and delays the inevitable.
Ultimately, there is no right answer to this. The greater the population, the greater the problem. If everyone who could work remotely started doing so, and the rest were afforded decentralized centers for the onsite labor they must do, this would be a more manageable problem. But eventually, we'd be back where we started - it'd just be a higher concentration of onsite workers generating all the traffic, and they might have less distance to travel.
Coruscant's traffic problems, or maybe 5th Element's, are what we're destined for.
