Sweet! If we're removing the subsidies us drivers get, are we also removing the taxes on gas we pay? Those are supposed to go towards road repair and infrastructure. To be fair if you remove the subsidies, you also have to remove the taxes as well - since cyclists don't buy gas and we're talking about levelling the playing field, the government would need to find a new way to charge everyone fairly (cyclists, motorists, delivery co's, TTC). This also means more government jobs, not less.
You do realize maintaining all those roads is what helps move our economy along. You can call it a subsidy if you like, but it's the cost of running a thriving economy. No matter what, goods and people have to get places that public transit and bicyles can never match.
If you tried to charge people 'the real cost' and price them out of cars. They won't go to the store across the city to buy something. They'll order it online - and have a heavy truck deliver it - if they can still afford it, since in your theory, the costs would become enormous on the delivery company and they'd be passed on to the consumer as well. So now, no one can afford anything, and the economy slows.
Due to the nature or location(s) of some peoples jobs it is impossible for them to use any other form of transportation other than a car, so it would be an unfair burden to people in those types of jobs as well. Plus, the auto ain't going nowhere anytime soon. whether it's electric powered, internal combustion or flux capacitor powered, there will always be cars - and driving commuters.
