I'm guesing they all have access to at least trans-sonic speeds.

What? That can't possibly be right! No way any of them go that slow!

Arravan said "at least". meaning trans-sonic is like walking to them.

Is it just me, or is Accel's hand in an awkward position and poorly proportioned?

It's not just you. Trial Memory is drawn incorrectly, the throttle isn't able to be held while it's inserted in the belt.
