Intersection negotiation task decentralized behavior to avoid collisions

[kevin-thankyou-lin]

Hey @eleurent, thanks for the awesome work!

For the intersection negotiation task, have you considered a 'whoever comes first, goes first' decentralized policy?

For unregulated intersections (i.e. no traffic lights), I think this is the default rule for some countries.

That seems like a good idea indeed!
