Show planned turns via an arrow on the back of the rider

This would help to know which way I am going as well as someone that I might be riding with.

Already there on the back of the saddle, no?

Already does this, the arrow flashing under the seat.

are these obvious enough? Or do we need to make them clearer?

I think they are pretty clear.

I missed that completely. The are not that obvious, I am using an iPad so maybe my screen is too small.
