Why do conservatives love gas and cars?
Basically having a car gives you freedom of travel where you want when you want.
And why do they hate electric vehicles,
Electric vehicles in today form just fucking suck. Self combustion way greater than traditional cars. Less range per recharge. Limited amount of recharge stations and recharging a car taking at least 30 minutes makes them insanely inconvenient compared to normal car what can drive more further, you can find fuel stations in total shitholes and refueling takes less than 1 minute.
solar power,
Solar panels are just not efficient enough yet. They could make a good support power source(like some sort of portable solar panels that could be useful for travelling or some next to your house for smaller fees for electricity) but still we will have to rely either on burning fuel energy or nuclear energy in order to satisfy our electricity needs, nuclear power is the best for now as it produces a lot of energy while its not polluting at all.
and walkable / 15 minute cities?
Its not a bad concept on paper as it would be convenient to get everything in range but its just impossible to make. And most likely our shortsighted goverment members will just mindlessly divide cities into ghettos and force people to stay in their own ghettos(you dont have school or any reliable job at your ghetto? Too bad, we dont care lol)
And why do they hate public transportation?
It fucking sucks, it is just insanely fucking inconvenient for anyone but NEETS, Hobos and other jobless fellas. Also safety of these is very low because of thieves, robbers and other kind of shitfaces being there.
Why do they want everyone traveling by some stupid gas-powered vehicle that pollutes the environment and contributes to health problems like increasing the rates of asthma among inner city children?
Its just mostly the only option avaliable that is not inconvenient.
And why do they dispise bicycles?
Lack of bicycle roads.
