Some cities are car-centric because we designed and subsidised infrastructure to make it so. We induced a demand for cars by spending billions on building, expanding, and maintaining highways to the point that people hop in their car for a 2km trip. People now have no choice of transport other than a car, and that's a problem. It's literally killing us and our children whowith road violence, lung cancer from emissions, and via our climate.
Your steakhouse metaphor is akin to the entire city consisting almost exclusively of steakhouses. But why bother changing it, all cities are designed only for steakhouses. You don't get a choice to eat other cuisines because it's so inconvenient to go across town to the one Greek restaurant.
You'd be shocked at how little traffic violence is treated as manslaughter. In Ontario, Canada, a lady only got a temporary driving suspension for driving through a group of girl guides at 120km/h in a school zone, killing one and injuring several others. The driver even denied responsibility in court.
The public dialog is still that pedestrians and cyclists need to be careful around cars with victim blaming when people are hit. When school starts, the kids better be careful. Where are all the signs and messaging around how drivers need to be careful? I constantly see drivers speeding and rolling stop signs in school zones but it's completely normalized and shrugged off.
