I think @blabberbeak's questions are related to TruckersMP, and should be asked.
"What types of cargo or missions would you like to see added to the game?"
TruckersMP has added a number of custom cargoes and job-based "missions" to the game in the past. Examples include Operation HQ, Fruity Fiesta, and the TruckersMP Logos. Asking people what they might like to see in-game may enable TruckersMP to add more custom cargoes and create additional job-based "missions" in the future.
"Do you use mods or user-created content to enhance your game experience? If so, which types of mods are your favorite?"
Currently, only a limited number of mods are supported. Asking a question like this may pave the way for the inclusion of more mods. Contrary to the assertion that TruckersMP has no influence over the base game mod support, this is inaccurate. TruckersMP has the autonomy to support whichever mods it chooses, thanks to its own mod manager. Furthermore, if you categorise "smart signs" as a mod, TruckersMP has the capability to develop its own mods as well. This question is clearly aimed at TruckersMP although, the same question could be asked to non-TruckersMP players.
"Would you like to see more official support for modding and user-created content within the game?"
What I said above applies here too.
"How important is the ability to customize and personalize your vehicles in the game?"
Not 100% on this question, but I'd assume it has something to do with implementing fixed profiles so everyone has the same set of trucks with the ability to do very little modification. Probably to make everyone's experiences more realistic, as you don't tend to see fully blacked-out trucks with more lights than a Christmas tree in real life.
"Would you like to see realistic trucking challenges or regulations (e.g., rest periods, weight limits) incorporated into the game?"
If a strictly realistic approach were developed, players might wish for rest periods to be enforced. They may also desire the ability to not carry more weight than laws allow, alongside adherence to other real-life regulations, such as working hours.
"How important is it for you that the game accurately reflects real-world trucking regulations?"
This ties in with the question above; some players may wish for a more realistic experience.
The other two questions also link into what I've already said, so I won't mention them again.
Everything asked, as far as I know, can be added. Therefore, why shouldn't these questions be asked? It's been suggested time and again that the game should be more realistic. These questions seem to be aimed at gathering an idea of how many people support such a suggestion. TruckersMP most likely has control over how realistic they wish to make their modified version of the game. SCS has a near-zero impact on that.
