If my post did in fact insult you or your friend who use the same account i am sorry for that, but you have to admit that the first post sounded quite silly and amusing when you first read it with designing audio-systems that play music when driving around the track in a game that won't have a driving-feature built in to begin with, let alone a music-player, that is quite far-ahead of even what's planned so far.
One should really take things as they are at present and go from that, read some topics on this forum on what is in and what is out and preferably consult the list of -> probable <- features to be included in the final game
(which you can find
here) before posting stuff like audio-systems and test-driving when it explicitly states that driving your cars is not a planned feature at all.
No offence, but imagine yourself registering on the forums of the next "Modern Warfare" game and suggesting that the players soldier should be able to get a MP3-player and headphones playing death-metal during online battles or that the player should be able to pimp out a Humvee with 22" crome or golden rims and mount it with hydraulics in a garage before battle. A post suggesting that would become quite amusing too i believe.
Finally, concerning SLRR it's a whole different world from this product. In SLRR you buy a wrecked or new car at the dealership, take it to the garage and tune the heck out of it, mount a wing you stole from a jumbo-jet onto its trunk and then participate in drag-races in a flimsy, silly and generally broken physics and graphics engine until you smash your ride into a wall/bus/lamp-post/whatever and begin anew. The only economy-aspect of that game is how to get the money to afford a new turbo so you don't get fined by the police. I should know, i played it from basically the day it was "released".
But true enough, the engine-designing aspect of Automation does have some vague resemblance to the engine-building aspect of SLRR, i'll give you that, and the community of that game is still thriving to this day and releasing everything from small fixes to complete super-modpacks for the game both better and worse.
So, as said, i apologize if i insulted anyone, but to be honest you kind of had the jokes coming at you to begin with.
