I think D5 should definitely look into enhancing their car path simulations with traffic simulations . Chaos just released a new update with envision that allows you to draw car paths and it actually simulates car traffic and suspension . Intersecting paths automatically work with each other , some cars will stop and allow other paths to go like in real life . You can even see the tires and cars move like they would in real life for animations . Also cars will stop for people if they intersect roads, plus you can animate doors opening and closing with the intersection of people walking .
