Arcade servers are one option for security, rollback and simulation among others. Many people choose simulation servers - you can see that from the statistics. The road to simulation is paved for a reason. But also for those who want to play a more complex simulation, there is the VTCW (VTC.World) project, for example.
In my opinion, this discussion makes no sense. The Arcade server is one option, and everyone can see the attendance of players. Yes, there is an option to avoid collisions, but collisions is both realism and incorrect behavior of some players, unfortunately. That's why there's a GM, there's a Community that sends game reports, and they're reviewed.
Correctly stated above - we're playing trucking here.
