While driving home tonight I had a sports car cut me off, then weave back into the other lane. He had no compunction about speeding, cutting people off. However the far lane from me was the bus lane, which was empty. This guy preferred to speed, weave in and out of traffic, narrowly missing causing car accidents, yet he somehow felt that abusing the bus lane was beyond what he was comfortable with.
In the end on the highway, he had gained himself 3 car lengths and about 10 seconds time. But had caused almost 5 accidents to get it.
