Gaps and Lane Changes

This lesson runs in the same lab as lesson 1, with the attackers still switched off and your WeaveMeter on the Game entity.

The civilian branch

Lesson 1.7 promised three habits. A civilian that catches a slower car follows it, or changes lanes when there is room. Where a lane ends, its cars merge. All three live in one branch of stepDriver, the one every civilian runs when it has no one to attack.
