Why does the game feel so lifeless?

Recently i started the game again id say im pretty og ive known the game since like 2017 maybe i never truly finished it, the farthest i got was finishing the car and delivering it to fleetari to get the wheel aligment and shit but, after that for some reason i had many saves but i dont think i really experienced the game fully, today just for fun i downloaded someones save, i drove around and i just realised that msc feels kinda like lifeless like nothings happening, i miss the two shitbags at the teimos store other than annoying teimo and sometimes driving over a random dude ( now you can go to jail for that so not that fun ) you cant really do anything, ive always loved this game but just to be honest it kinda just seems empty
