    Texting is almost completely free for carriers.

    The vendor's price is mostly irrelevant when choosing the selling price. It's mainly used for deciding how much product to put on the market. If you price above the market because your costs are so high, then you won't sell any. If you price significantly below the market because your costs are low, you'll be throwing away money.

    Don't blame the "evil overlords" for the high prices. Price gouging isn't a market failure—a monopoly is.

    Someone driving on a heavily congested road bears the same cost of congestion as everyone else around him -- and is contributing to that congestion just as much.

    We don't use time as a form of money here. If we did, there would be no "shortages," there would only be really long queues.

    Drivers already bear the cost of traffic congestion.

    But not in proportion to the amount of traffic congestion each driver causes.

    We can permanently eliminate traffic congestion by allowing supply and demand to settle on the equilibrium price of travel. This would save us all a LOT of money that would otherwise be needed to expand freeways just to relieve traffic congestion.

    Putting an environmental impact fee (tax) on fuel would be a more reliable compensation for your impact than GPS.

    Actually, the gas tax only covers your emissions. It doesn't cover your impact on traffic congestion, which is higher when the road is congested or approaching it; it doesn't cover wear and tear on the roads, which is proportional to the fourth power of the weight of the vehicle (the gas tax is only proportional to the first power of the weight of the vehicle); and it doesn't correct for the fact that bridges are much more expensive to construct and maintain than at-grade roads in rural areas.

    #1, if everything is a toll road in congested areas, the areas that have higher tolls between the living area and the working area will be depressed in value...

    Why not let the free market decide what properties in sprawling suburbs far from work centers is worth?

    #3, just because there's a toll making it more expensive to get there, doesn't mean that there'll be any less traffic...

    Of course it does. Look at a demand curve. As price rises, demand falls, so if the price is high enough, demand falls to the level of supply and the shortage is eliminated.

    Why price the tolls on the highways according to market when you can make more money due to your captive market?

    If you want to make more money, build fewer lanes. Then you can price the tolls according to the market and also make more money.

    And then you have the other side, the people who refuse to spend the money on the tolls and use the side roads rather then the highway.

    If the freeway lanes are nearly full because you've correctly priced them, then you can hardly blame the tolls if people are also taking the side roads!

  9. Efficient pricing makes congestion obsolete on L.A. Artist Contemplates Future Traffic Flow, With Hot Wheels · · Score: 1

    Given that traffic congestion is a type of shortage (a shortage of available space on a road at a given time of day), and that a shortage happens when when the price of an item is set below the going rate determined by supply and demand, the solution is made obvious: raise the price of freeway access just high enough to eliminate the traffic congestion, but no higher. Then lower the toll when demand is low, to give people the ability to economize. Variable tolls permanently eliminates any need to expand the freeway just to eliminate congestion. There are other ways to justify expanding a freeway, but congestion is no longer one of them.

    Efficiently pricing freeway access saves a lot of money that would be spent expanding the freeway. For example, the USA's Congressional Budget Office found that southern California's SR-91 express lanes generate net social benefits of at least $12 million per year, compared with a scenario in which the lanes had been built but drivers did not pay to use them.

    Because many if not all states currently fund freeways with general sales tax revenue, As a group low-income residents, on average, pay more out-of-pocket with sales taxes" for freeways than with tolls. Therefore, tolls are less regressive than the alternative.

    The free market works remarkably well, when it's allowed to work.

    Please explain more carefully how using more trucks and truckers to haul the same amount of goods would save us all money.

    Making it illegal to pass on the right will only result in all drivers packing into the left lane as they do in states where that is the case.

    Which states?

    People tend to drive at speeds that are naturally supportable by road conditions and only respect posted speed limits if they are reasonable.

    Unfortunately, most people overestimate their driving abilities. Therefore, they tend to drive at speeds faster than are supported by road conditions.

    Extending your logic, the tax bill on an 80,000 lb 18-wheeler that hauls food to your local grocery would be 2.56 million times the taxes paid on a 2,000 lb car.

    I oversimplified a little. Road wear is actually proportional to the 4th power of the axle loading, and tire size also comes into play. In the end, a 40-ton truck does as much damage to the road as (only) 9,600 cars.

    And because a 22,400-lb axle load causes 6.4 times as much road cracking as an 18,000-lb load, making truckers pay their fair share of the road wear would encourage them to haul lighter loads to save money. In the end, it would save us all money.

    How on earth would making it illegal to pass on the right cause slow traffic to stick to the correct lane?

    Because they would be impeding traffic if cars can't pass them on the right. So they will pull over under threat of being cited, as on the Autobahn.

    And even if the slow traffic *does* stick to the far right lane, how is that going to make it easier to merge into traffic? The main problem with merging into traffic is the fact that onramps are generally too short to get up to speed...

    ...when the traffic in the right lane on the freeway is moving faster than the speed limit.

    We already have a close proxy to this with the gas tax. The weight of a vehicle is a large determinator of it's fuel efficiency.

    A 2-ton vehicle uses only about twice as much gas per mile as a 1-ton vehicle, while causing 16 times as much road damage. Therefore, the gas tax is a completely inadequate way to pay for the road wear.

    On the Autobahn, it's illegal to pass on the right, and that is part of the reason why it's safe despite the lack of speed limits.

    Lower speed limits: two birds, one stone.

    Yes, lowering the speed limit or at least enforcing existing limits, would reduce fatalities, attract smaller engines, make larger vehicles more fuel-efficient, and optimize traffic flow [pdf]. So I'm counting four birds with one stone.

    Another "two birds, one stone" solution is to make it illegal to pass on the right. Then slower traffic would always need to be in the right lane in order to avoid impeding traffic, and that would (1) make it easier for smaller engined cars to come up to speed on freeway onramps, and (2) separate slow traffic from fast traffic.

    Because road wear is proportional to the fourth power of the weight of the vehicle, make the 4,000 lbs SUV owner pay 16 times as much in taxes as the 2,000 lbs small car owner.
