What kind of rollercoaster do you wish existed?

Imagine a Greek archer pulling back his arrow. The ride will start with people in an upwards or downwards projection angle, and then they move a little bit out of the return space, and then the platform will change the projection down or up to connect to the rest of the rollercoaster track. As soon as the track is settled, the archer let's go of the arrow (of) people, and they go off speeding like an arrow in the wind. It could be 1-sided or 2 sided cause an archer always has to reload.
It's more about the concept than the actual ride.
