What is a formal synonym phrase for cutting lane barbarously?
I know it mean move to another lane, but what about we want to express its barbarously action?
In such a case, I would use the adverb "rashly" or "aggressively" to describe the cutting of lanes.
The distracted driver changed lanes rashly without checking for traffic
The driver changed lanes aggressively cutting across the path of a schoolbus
The difference between rashly and aggressively is the driver's attitude - a rash driver does not drive safely, does not check before cutting lanes. An aggressive driver - while also rash - has a bullying attitude.
