A minecart booster currently chooses which way to boost as follows
1. If motion in one direction is blocked boost in the only possible direction
2. If the cart is already moving - boost in that direction
3. If cart is not moving or blocked but is on a slope - boost downhill
That means if a cart is sitting on a booster which powers up on a flat
straight track, it will just sit there. I would like to add additional
factors to the end of this list as tie breakers so that it becomes possible
to make a simple one direction launcher or to tell the booster which way
to boost in situations where currently nothing would happen using only
redstone circuitry.
I invite discussion of the details of how this could be implemented from
redstone experts. However I suggest that a good basic principle for a
proposed rule 4 would be that the booster prefers to boost towards powered
locations. In other words the booster checks whether adjacent squares are
powered from a source other than the booster itself. If the answer is yes
in one case and no in the other then it pushes towards the powered square.
This rule would make the following simple one way stop-go launcher possible.
One neighbour is "more powered" than the other, so when powered up the
booster would push a stationary cart in that direction. Note that the
adjacent square in one direction is powered by a source other than the
booster itself. This would make a good rule.
A slightly more complicated setup for controlling launch direction
with buttons would then be (front and back view)
This would make it much easier to build stations.
As it simply adds a rule 4 it makes no change in situations where
the existing 3 rules determine direction. Hence it would not break
any existing functional minecart tracks as far as I can see.
Powered the direction of the source? Would that not make it impossible to power a series of boosters?
It is only a rule 4. It would only change current behavior if the cart wouldn't move
at all under current rules. So it wouldn't break functional minecart systems.
You could still power a bunch of boosters with one source.
Personally I don't like proposals which involve adding a lot of specialised new blocks. To me part of the appeal is the ability to build amazing things from simple components. The proposal that I have made does not add new blocks. By making a very tiny subtle change in behavior it makes it possible to do a lot more powerful things with existing blocks without breaking existing structures.

Mostly moved on. May check back a few times a year.
