The fact is, you are making a lot of unreasonable assumptions.
Your car example is bad. A car is very different to a game, a game (or at least the type of game that is going to be sold back to a store) is only fun when you haven't experienced that part of the game before. Nobody says, well, it's boring driving my car to the shops, because I've already driven it to the shops once before.
Additionally, people sell their cars 2nd hand after about a year. A year old car competes with a new car better than a 2 month old single player game competes with a modern single player game, because everyone who cares about it has played it.
You accuse used games of driving developers out of business, and then demand that small developers halve the price of their games? The truth is, the ability to sell games second hand increases their value - people are happy paying more for a game they can resell later. In addition, people use the money they make selling games to buy new games, helping to fund developers further.
Honestly, you have no clue about the actual implications of these things you suggest.
Note how developers that make high quality games (Nintendo is the best example) never bitch about used game sales. I will never sell any of my Nintendo games, probably not even when the sequels to them come out - I might still want to play MK:Wii for the courses that are in there. Make good games that people will want to keep, if you want to stop used games sales and have people pay full price for your games.
