Haul Truck too underwhelming for its cost: Desperately Needs a Buff

A single Haul Truck is more expensive than three T2 Trucks: it requires additional 30 Electronics II to be built.
At the same time, it is less effective than two T2 Trucks: given that it moves at 36% less speed, at maximum speed it would carry only 114 items over the same period T2 Truck carries 60.
But actual T3 Truck throughput is even worse, because:
- Its acceleration is three times lower.
- While Mega Excavator loads a T2 Truck almost instantly to full, it would require two additional turns to load a T3 Truck.
- Not mentioning that you need more to adapt your traffic infrastructure to T3 Trucks.
I think it would be fair to raise the capacity of T3 Truck twice - to 360 items - to justify its cost, so it could fill the entire T2 Storage at once.

Right now, they're specialty vehicles which are a bit better than normal trucks at mines, but are disastrously bad the moment they have to deal with belts and pipes.
The initial build cost isn't much of a problem for me; they'll be with you so long they're amortized down to nothing. What I do care about is the doubled fuel/maintenance costs for a vehicle that is only about 2x as effective if you completely baby it, and is often substantially worse than the standard truck. I can't tell you how many times I've seen haul trucks take deeply stupid paths or take on jobs they should know they can't complete.

I think they are intended to be confined to mines. IRL you would never see a truck like the mega's hauling anything outside of a mine. The intent is large amounts of product, short distances.
If you utilize them that way, does it make a difference you think?
