Huh, so you paid for the road and the cyclist didn't? I'm not an American, but I don't think there's a road tax for car owners in the US.
Fuel taxes (which never pay for all of a road - general taxes pay for them as well) don't even cover the disproportionate wear and tear for necessary maintenance from vehicles. So in reality bike riders and people who don't ever use roads subsidize the roads for car drivers. It's NOT car drivers paying for all of it, they don't even pay their fair share based on the ongoing maintenance burden they impose on the roads.
There really is no acceptable, rational reason for animosity towards cyclists. I think it comes down to the same gut instincts as racism, sexism and xenophobia - when there’s a problem people look for whatever thing seems most different in their current surroundings and blame that thing for the problem. It’s just a lack of thinking.
No rational reason for drivers in a road predominantly used from big vehicles to not like smaller, hard to see, vehicles with greater flexibility and much more fragile going around them?
The added care you need to have as a car driver, and danger they impose of accident, is not enough?
Especially since most of the time (e.g. in highways, interstates, etc) you get to have the road to just cars and don't have all this?
And cars also put the vast majority of the wear and tear on the roads. So while they might pay more overall, they don't pay their fair share compared to bike riders who fund the roads from their taxes. Bike riders (and people who don't use roads) end up subsidizing roads for people who drive cars.
Of course, on residential roads, they don't usually have many large trucks. Also, in areas with snow, it seems that snowplows actually cause most of the potholes.
In many other countries those are even worse, including added state taxes on fuel, and so on.
I generally find the tone of the discussion about cyclists here surprising. I'm from Germany, and while there is animosity between cyclists and car drivers, both are equally accepted on all roads (except the autobahn, of course). There's a movement in big cities towards more and more specific lanes for cyclists. I don't own a bicycle myself, but with regards to a car's emissions and the omnipresent wasteful parking slots, I'm all for strengthening the status of cyclists on roads.
