Car depend infrastructure is amazing to families. A mom can take her children to the grocery store in a car in relative safety without worrying about mentally ill homeless people on the subway.
Perhaps the subway itself isn't the problem...
fixing homelessness doesn't make me money
Car dependency and castle doctrine is essential in a low trust society with a legal system that puts violent offenders right back on the street.
Driving is more dangerous, and it's not even close. For example, in NYC you're over 100x more likely to die in a car on the roads above the subway than on the subway.
Only the most naive of the naive can believe being a safe driver means they won't die in a car wreck.
