I think that this /fix system should be in effect, but only who really care enough to obtain such an ability.
I'd say that these people would have to at least have:
No bans in the last year
1 Year and a Half's Time registered with TruckersMP
250 Hours In-Game (I'm sure this could be done because it has been done with the registration of the game from Steam to a TruckersMP account, the 2 hr thing)
Then, they could have access to an exclusive page on the TruckersMP website that would allow them to gain the access to the command in their In-Game accounts.
Please let me know what you think of this, everybody reading, by casting a reaction or commenting CC
