I imagine a total fail. The car is programmed with an expectation of fairness - it assumes folks stop at lights, observer lanes and take turns at intersections, at least most of the time.

In those other cities the locals would learn to game the autocars, taking the initiative from them at every interaction, leaving them impotently idling at a busy intersection waiting for somebody, anybody, to give them an opening.

IIRC, they're working at "fair but not doormat" - yes, gameable, but not so supine as to wait until the rush hour is over before nosing forward to indicate a desire to turn.

Need to review films of rush-hour traffic in Delhi. Cars stream pell-mell through intersections as a living fluid. No such thing as nosing forward to indicate anything. Its a whole different world.
