If that was the case with the car, they wouldn't have added two more cars since one could clearly serve the purpose you mentioned. Also, there wouldn't be another car only for patreons either.
Whether it's highly unlikely to be added, i leave that on the TMP management.
Last year i suggested a Casual Server to be added to the game. A few months later, they started inquiring about the speed limit and a month ago they gave us Sim 2 as a casual server.
So please by all means, stick to Sim 1 and stop feeling the need to point out to anyone that likes a more casual playstyle to play a racing game.
