If I remember rightly, this is more about local/regional multidrop than ETS's cabotage/tramping setup - although it mentions nothing like that on the Steam page (maybe I got it from a forum?). If this is the case, then there are a number of problems:
- Multidrop work is mostly fiddling around with difficult access in small town centres, residential deliveries, farm deliveries, etc. This map appears to feature mainly extra and interurban roads
- Loading and weight is a bigger element of driving than trunking - you have a diminishing load which you have to calculate after each drop to work out your CoG (You feel your CoG shifting a lot during your shift... is this a physics element this game includes?).
- Multidrop IRL is not fun, and is inherently not fun in a game. On multidrop, 50% of your time is working, the other 50% driving, so there wouldn't be much gameplay
- You'd really need an 'on foot' element to make such gameplay workable, even if it's just switching to a forklift to offload the correct pallets.
Of course, I could be completely wrong, and they've moved away from multidrop to W&D trunking (i.e. trailer swaps). If this is the case, they've saved themselves a lot of effort, but have swerved right into the path of ETS, which is not the place to be.
