Re: lack of self cancelling indicators/ bells/ whistles...
The point is the equipment on the Atom is the bare minimum of what is needed. Self-cancelling indicators are not needed, they're a luxury, so they go.
FYI my motorbike doesn't have self-cancelling indicators either, but it's hardly a chore to press the button with your thumb to cancel them after you've turned a corner and provided you check your instruments as part of your Information phase (you do scan the road ahead, mirrors and instruments regularly, don't you?) you'll notice if you've left them on.
The Atom isn't a practical car, but if I could afford one, I certainly would buy one *and* drive it back from Nice (admittedly ensuring I had a decent set of Textiles to wear...)
