I will ignore the shouting for bikes-should-pay, transit-doesn't-pay, etc. since these comments quote opinions and not hard facts. Here are some of the latter.
Roadways are funded by a mixture of (decreasing revenue from)gas taxes -40%, PDC funds, federal grants, property taxes, bonds and local improvement district funds.
One automobile - requires 3000 sq. ft. of roadway to park (in a lot) and 30,000 sq. ft. (0.7 acre) driving at 30mph. All of the intersections with 3-digit crash rates are more than two lanes in each direction (which encourages higher speed). The maximum capacity for a roadway is 2000 motor vehicles/hour.
By contrast bicycle transportation consumes 75 sq. ft. per vehicle (at 15 mph). A bicycle causes 1/10,000 the damage to the road surface that a car does. Assuming an 11ft travel lane, a lane would have a capacity of 30,000 bicycles/hour.
An urban train system has a capacity of 40,000 passengers/hour.
Due to the higher efficiency, I encourage the city to continue pushing for high-capacity transportation solutions.
