Your guess is as good as mine but it is probably safe to say mistakes were made, lots of mistakes.Context, plz...
Given the location the most likely perpetrator is either a drunken or Asian sorority girl. Initial speed was not likely the cause of the accident but a lack of understanding of what the round thing below the visor mirror and the funny things on the floor do.Jeezus - how fast do people need to be driving on residential streets for $hit like that to happen?
