Combining ‘gap technology’ and ‘lane changing’, reveals a lot about an individual. It reveals their awareness (reading traffic), timing and handling skills. …Did they use their gap when preparing for the lane change? Did they accelerate to fill a large gap thus creating minimal or no deceleration or did they unnecessarily decelerate and/or cause others to decelerate?
And if slowing was necessary, did they use their gap wisely in order to minimize its affect on others? …How do they continue to use their new gap after the lane change?
