- if truckers can maintain a bubble, how can it be impossible?

- yes, aggressively weaving drivers sometimes jump in ...then they jump out again.

- at merge zones, the entire point is to let people into your lane.

- In theory, everyone else wants your precious bubble. In practice, not.

...and in a burning building, we all know the best way to escape, eh? EVERYONE AGGRESSIVELY PUSH FORWARD, DON'T LET ANYONE ELSE GET PAST, COOPERATION AND TEAMWORK ARE FOR LOSERS! Yep, that certainly won't trigger a huge clogged mess where everyone dies.
