The reason you took a long time to understand "replacement cost" as a charge from dealers is because it is utter bullshit. I bought a briefcase the other day, and paid for it based on what the seller had paid, not on what the seller is GOING to pay for his next bit of stock. Once he gets the new stock in, the then raises prices.
Carpooling? Uh, I live in the country and work at home. Not effective. Actually, not possible. I use about one tank of gas every 2-1/2 weeks in my pick-up (Chev S10 gutless wonder). We probably use more in the car, but that's a 30 MPG Stratus (Dodge's ultimate POS). We time our town visits so when I need something, my wife does shopping, etc. Believe me, that's a royal PITA but probably will become more and more necessary as time goes on. I also don't zip into town for one item anymore, unless it is essential to the success of an article that is deadlined.
I may be back on a small motorcycle soon, though I quit riding when I moved down here 28 years ago. If there is still a 250cc road bike out there, or even off road, I might be able to up my 25-30 MPG vehicles to
55-60 MPG. I don't always need even a small pick up bed for my treks into town, nor do I need the extra space in a car to go to, for example, the library.Yeah, all that said, I'll be heading to the truck terminals in Roanoke (about 35-40 miles away, call it 85 miles round trip) in a buddy's over-sized Ford pick-up to grab two jointers for an article. My truck won't handle the size or the weight, so I buy him at least 20 bucks worth of gas for that one trip. Probably $30 just to be nice.
