No, analogies compare concepts and ideas. You were using it to compare products, and it doesn't work, because a new car comes with a warranty, and any problems with it can and will be fixed otherwise the vehicle can and will be replaced. It's even more optimal to get a different car than it is to just play another game, because with a car, you can get your money back/get a replacement. Unless you were stupid enough to buy a car without a warranty, in which case, that's on you.
Elite, on the other hand, is a piece of software, and indeed, the guarantee is reversed - it WILL have problems, because that's the nature of software. You also don't own your game the same way you own a car. You own a software license, but you don't own the software. You never will, and hence, have no legal say in how it's operated. Your only option here is to forgo the license, and cease buying anything in relation to it. Move on, and put your money somewhere else, ie in another game.
A better analagy would be television. Don't like what you're watching? Change the channel. It really is that easy to just play another game, especially if this one is as bad as you're claiming.
