"The infrastructure and subsidies did not cause the automobile and air traffic boom, it was created by the automobile and the air traffic booms."
the automobile industry forced the government into allowing cars in downtown city districts and building parking lots. had things gone differently, car traffic would be exclusive to freeways outside of the city and rural roads. instead, however, we have cars hindering productivity within cities. in downtown orlando, fl, alone, 2 freeways intersect and take up a huge portion of the central district.
"And actually the infrastructure wasn't there until closer to the mid 70's. It was by then that a car could travel across country and not have to worry so much about finding gas stations."
the 50s infrastructure i'm referring to is suburban housing developments which exclusively had single-family homes with driveways; what we call "suburbia." this is where commuters lived and due to being far away from places, homeowners needed a car just to go shopping.
in the 70's there was an oil embargo that forced gas prices to increase. as a result, american auto markets began losing out to japanese imports that prioritized fuel efficiency. this is why you see people like me driving a 1999 honda cr-v. as a result, your car could carry you further and made the gas stations less of a concern.
"Do you seriously think that the government is full of experts on everything? Safety standards have been evolving forever."
the private sector were never going to implement safety measures universally. given the choice, i'm sure american airlines would've never wanted 9/11 safety measures even though their planes were the ones that plummeted into those buildings. the private sector almost certainly have experts in the field. that's why i praise the engineers at spacex and the marketeers at brightline. that extends to safety as well. however, as you say, it's not universal. chevron has priority on the condition of workers, while exxon does not. i never said the government came up with airline safety standards, but they had to be the enforcers.
and george bush certainly needed damage control after 9/11 ;)
"Taking the train I get to work in a little over an hour."
in countries with modern infrastructure, most commuter trains are built to be faster than their driving alternative since roads designed for faster cars tend to be less safe for both drivers and cyclists, while the trains are modern and have better design philosophy.
