Issue description
It is probably a design decision to make the demolishing of belts to be extremely, extremely slow on the RK2 belts, and even extremely, extremely, extremely slower demolishing of RK3 belts. I'm sure this will be the same issues if/when higher speed belts/pipes are added. I can delete a long belt, let's say 50 squares long. I turn up the speed to 3X and wait. Then wait some more, then a little more waiting afterward, After this period of waiting for the belts to demolish, I could have read a novel, made dinner, fixed global warming, and even possibly secured a date with Elizabeth Shue. The 1994 version of Shue, not the current version, just in case that needed clarification.
Spending unity to demolish anything is a superb idea in your game, it really is a fantastic addition, kudos for it, really. I am all for having to wait to demolish higher ranked items, they should be more difficult to demolish, but I honestly think that the time to demolish a RK3 belt is really, really, really slow.
So this would definitely be an idea to propose, I also think that there may be a bug in it. Again, this could have been a design decision, but it doesn't make much sense to me. A 80 tile long RK3 Flat, vs a RK3 U-shape takes twenty seconds longer. It takes 30 seconds to demolish a 80 tile long U-shape transport, versus 50 seconds to demolish a RK3 flat transport. So that is .375 seconds for each square of a U-Conveyor, and a .625 second demolish time for a Flat Conveyor. All these tests were conducted at 3X speed also, I didn't want to have to wait an hour for belts to demolish ;)
RK3 Flat Transport and U-Shape transport both take the exact same number of construction parts. The Flat definitely has a much longer demolish time.
I will submit this as an idea also, but having to wait a long time for a belt to demolish on 3X speed is a bit excessive, I think.
As another note, I tested this on every belt/u-shape transport, levels 0-3, loaded and unloaded on the U-shape. The times were exactly the same whether the belt was loaded or unloaded, and didn't make any difference on whether or not it was raised or not. I didn't check the loaded times for the belts, but if they were anything, it was probably longer.
Expected behavior
Nothing really, just the length of time to demolish a transport seems off. Belts should demolish at the same time, I also think that they should be faster.
Reproduction steps
Make a long belt. Demolish and time the belt.
Game version
V0.4.9 (experimental) but same happens in stable release.
